Copying ENI metrics was done in callout context, this caused the driver
to panic when sample_interval was set to a value other than 0, as the
admin queue call which was executed could sleep while waiting on
a condition variable. Taskqueue, unlike callout, allows for sleeping, so
moving the function to a separate taskqueue fixes the problem.
ena_timer_service is still responsible for scheduling the taskqueue.
Stop draining the callout during ena_up/ena_down. This was done to
prevent a race between ena_up/down and ena_copy_eni_metrics admin queue
calls. Since ena_metrics_task is protected by ENA_LOCK there is no
possibility of a race between ena_up/down and ena_metrics_task.
Remove a comment about locking in ena_timer_service. With ENI metrics
in a separate task this comment became obsolete.

The ena_com_config_dev_mode() function performs many LLQ related
calculations and sends an admin command to configure LLQ in the device.
All the LLQ related operations are unnecessary if the driver fails to
find LLQ memory bar.
Move LLQ memory bar allocation to separate helper function
ena_map_llq_mem_bar and execute this function before LLQ configuration.
If the LLQ memory bar cannot be allocated, then LLQ configuration is
skipped.

(cherry picked from commit 2b766d5e5a)
In handleevents(), lock the timer state before fetching the time for the
next event. A concurrent callout_cc_add() call might be changing the
next event time, and the race can cause handleevents() to program an
out-of-date time, causing the callout to run later (by an unbounded
period, up to the idle hardclock period of 1s) than requested.
In cpu_idleclock(), call getnextcpuevent() with the timer state mutex
held, for similar reasons. In particular, cpu_idleclock() runs with
interrupts enabled, so an untimely timer interrupt can result in a stale
next event time being programmed. Further, an interrupt can cause
cpu_idleclock() to use a stale value for "now".
In cpu_activeclock(), disable interrupts before loading "now", so as to
avoid going backwards in time when calling handleevents(). It's ok to
leave interrupts enabled when checking "state->idle", since the race at
worst will cause handleevents() to be called unnecessarily. But use an
atomic load to indicate that the test is racy.

uma_timeout() has several responsibilities; it visits every UMA zone and
as of recently will drain underutilized caches, so is rather expensive
(>1ms in some cases). Currently it is executed by softclock threads
and so will preempt most other CPU activity. None of this work requires
a high scheduling priority, though, so defer it to a taskqueue so as to
avoid stalling higher-priority work.

To deal with broken session slots caused by the use of the
"soft" and/or "intr" mount options, nfsv4_sequencelookup()
will be modified to track the potentially broken session
slots. Then, when all session slots are potentially
broken, do a DeleteSession operation, so that the NFSv4
server will reply NFSERR_BADSESSION to uses of the session.
These changes will be done in future commits. However,
to do the DeleteSession RPC, a "cred" argument is needed
for nfscl_reqstart(). This patch adds this argument,
which is unused at this time. If the argument is NULL,
it indicates that DeleteSession should not be done
(usually because the RPC does not use sessions).
This patch should not cause any semantics change.
