Update the OFED Infiniband core to the version supplied in Linux
version 3.7.
The update to OFED is nearly all additional defines and functions
with the exception of the addition of additional parameters to
ib_register_device() and the reg_user_mr callback.
In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband)
have both been made into completely loadable modules to facilitate
testing of the OFED stack in FreeBSD.
Finally the Mellanox Infiniband drivers are now updated to the
latest version shipping with Linux 3.7.

do drain (flush_workqueue() in Linux terms) but instead returns true if
the work was removed before it is run, or false otherwise.
Simulate this by removing the taskqueue_drain() and return the value
derived from taskqueue_cancel()'s return value.
This would solve a witness warning caused by calling taskqueue_drain()
with a non-sleepable lock held, like:
taskqueue_drain with the following non-sleepable locks held:
exclusive rw lle (lle) r = 0 (0xfffffe001450b410) locked @

This do not affect kernel without OFED compiled in.
