drm/sched: Optimise drm_sched_entity_push_job
In FIFO mode (which is the default), both drm_sched_entity_push_job() and
drm_sched_rq_update_fifo(), where the latter calls the former, are
currently taking and releasing the same entity->rq_lock.
We can avoid that design inelegance, and also have a miniscule
efficiency improvement on the submit from idle path, by introducing a new
drm_sched_rq_update_fifo_locked() helper and pulling up the lock taking to
its callers.
v2:
* Remove drm_sched_rq_update_fifo() altogether. (Christian)
v3:
* Improved commit message. (Philipp)
