[PATCH 2/2] gpu/drm: Eliminate DRM_SCHED_PRIORITY_UNSET

[Luben Tuikov]

Eliminate DRM_SCHED_PRIORITY_UNSET, value of -2, whose only user was
amdgpu. Furthermore, eliminate an index bug, in that when amdgpu boots, it
calls drm_sched_entity_init() with DRM_SCHED_PRIORITY_UNSET, which uses it to
index sched->sched_rq[].
