Subject: [PATCH v8 07/10] drm/sched: cleanup event names

All events now start with the same prefix (drm_sched_job_).

drm_sched_job_wait_dep was misleading because it wasn't waiting
at all. It's now replaced by trace_drm_sched_job_unschedulable,
which is only traced if the job cannot be scheduled.
For moot dependencies, nothing is traced.
