  - drm/imagination: Fix double call to drm_sched_entity_fini() Call sequence of double call:
    pvr_context_destroy pvr_context_kill_queues pvr_queue_kill drm_sched_entity_destroy drm_sched_entity_fini     // here pvr_context_put kref_put(..., pvr_context_release) pvr_context_destroy_queues pvr_queue_destroy     drm_sched_entity_fini // here Call to drm_sched_entity_destroy() from pvr_context_kill_queues() calls     drm_sched_entity_flush() + drm_sched_entity_fini(). drm_sched_entity_flush() ensures all pending jobs are     completed and drm_sched_entity_fini() ensures no further submission is allowed as per expectation from     pvr_context_kill_queues(). Double call to drm_sched_entity_fini() is misuse of the API so keep call only     in pvr_context_create() failure path.
