drm/nouveau: Fix race in nouveau_sched_fini()
nouveau_sched_fini() uses a memory barrier before wait_event().
wait_event(), however, is a macro which expands to a loop which might
check the passed condition several times. The barrier would only take
effect for the first check.
Replace the barrier with a function which takes the spinlock.
