[PATCH v2] drm/sched: Don't crash kernel on wrong params

[Philipp Stanner]

drm_sched_job_arm() just panics the kernel with BUG_ON() in case of an
entity being NULL. If the entity is NULL, subsequent accesses will crash
the particular CPU anyways with a NULL pointer exception backtrace.

Remove the BUG_ON().
