drm/scheduler: Remove obsolete spinlock.
This spinlock is superfluous, any call to drm_sched_entity_push_job
should already be under a lock together with matching drm_sched_job_init
to match the order of insertion into queue with job's fence seqence
number.
v2:
Improve patch description.
Add functions documentation describing the locking considerations
