[PATCH] drm/sched: Remove useless BUG_ON()

[Philipp Stanner]

BUG_ON() should not be used anymore since it crashes the entire kernel.
Its remaining usage is in drm_sched_job_arm() to check the entity
pointer. If that pointer is NULL, however, the problem will become
visible through a respective NULL pointer exception anyways.

There is no advantage in crashing the kernel as a whole.

Remove the BUG_ON().
