LinuxKPI: make linux_alloc_pages() honor __GFP_NORETRY 
This is to fix slowdowns with drm-kmod that get worse over time as
physical memory become more fragmented (and probably also depending on
other factors).

Based on information posted in this bug report:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277476

By default, linux_alloc_pages() retries failed allocations by calling
vm_page_reclaim_contig() to attempt to free contiguous physical memory
pages. vm_page_reclaim_contig() does not always succeed and calling it
can be very slow even when it fails. When physical memory is very
fragmented, vm_page_reclaim_contig() can end up being called (and
failing) after every allocation attempt. This could cause very
noticeable graphical desktop hangs (which could last seconds).

The drm-kmod code in question attempts to allocate multiple contiguous
pages at once but does not actually require them to be contiguous. It
can fallback to doing multiple smaller allocations when larger
allocations fail. It passes alloc_pages() the __GFP_NORETRY flag in this
case.

This patch makes linux_alloc_pages() fail early (without retrying) when
this flag is passed.

[olce: The problem this patch fixes is longer and longer GUI freezes as
a machine's memory gets filled and becomes fragmented, when using amdgpu
from DRM kmod 5.15 and DRM kmod 6.1 (DRM kmod 5.10 is unaffected; newer
Linux kernel introduced an "optimization" by which a pool of pages is
filled preferentially with contiguous pages, which triggered the problem
for us).  The original commit message above evokes freezes lasting
seconds, but I occasionally witnessed some lasting tens of minutes,
rendering a machine completely useless.

The patch has been reviewed for its potential impacts to other LinuxKPI
parts and our existing DRM kmods' code.  In particular, there is no
other user of __GFP_NORETRY/GFP_NORETRY with Linux's alloc_pages*()
functions in our tree or DRM kmod ports.

It has also been tested extensively, by me for months against 14-STABLE
and sporadically on -CURRENT on a RX580, and by several others as
reported below and as is visible in more details in the quoted bugzilla
PR and in the initial drm-kmod issue at
https://github.com/freebsd/drm-kmod/issues/302, on a variety of other
AMD GPUs (several RX580, RX570, Radeon Pro WX5100, Green Sardine 5600G,
Ryzen 9 4900H with embedded Renoir).]
