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 Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Acked-by: Chunming Zhou <david1.zhou@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
