drm/scheduler/sched_entity: Fix some function name disparity

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/scheduler/sched_entity.c:204: warning: expecting prototype for drm_sched_entity_kill_jobs(). Prototype was for drm_sched_entity_kill_jobs_cb() instead
 drivers/gpu/drm/scheduler/sched_entity.c:262: warning: expecting prototype for drm_sched_entity_cleanup(). Prototype was for drm_sched_entity_fini() instead
 drivers/gpu/drm/scheduler/sched_entity.c:305: warning: expecting prototype for drm_sched_entity_fini(). Prototype was for drm_sched_entity_destroy() instead
