drm/sched: Make drm_sched_entity_kill() a public function

Browse Source 
Some drivers do not care on teardown whether the last jobs pending in an
entity are actually executed before teardown completed. For such
scenarios, drm_sched_entity_flush() is not the ideal function since it's
intended to wait for jobs to complete.

Make drm_sched_entity_kill() public for that use-case and update the
documentation.
