gpu/drm: Eliminate DRM_SCHED_PRIORITY_UNSET
[ Upstream commit fa8391ad68c16716e2c06ada397e99ceed2fb647 ]
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[].
