drm/sched: Add locking to drm_sched_entity_modify_sched
Without the locking amdgpu currently can race between
amdgpu_ctx_set_entity_priority() (via drm_sched_entity_modify_sched()) and
drm_sched_job_arm(), leading to the latter accesing potentially
inconsitent entity->sched_list and entity->num_sched_list pair.
v2:
* Improve commit message. (Philipp)
