[RFC 2/2] drm/sched: Remove drm_sched_entity_set_priority

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at igalia.com>

Now that no callers exist, lets remove the whole misleading helper.

Misleading because runtime changes do not reliably work due
drm_sched_entity_select_rq() only acting on idle entities.
