drm/i915: use __GFP_RETRY_MAYFAIL
Commit 24f8e00a8a2e ("drm/i915: Prefer to report ENOMEM rather than
incur the oom for gfx allocations") has tried to remove disruptive OOM
killer because the userspace should be able to cope with allocation
failures.
At the time only __GFP_NORETRY could achieve that and it turned out that
this would fail the allocations just too easily. So "drm/i915: Remove
__GFP_NORETRY from our buffer allocator" removed it and hoped for a
better solution. __GFP_RETRY_MAYFAIL is that solution. It will keep
retrying the allocation until there is no more progress and we would go
OOM. Instead we fail the allocation and let the caller to deal with it.
