The uvc_video_enable function is calling cancel_work_sync which will be
blocking as long as new requests will be queued with the while loop. To
ensure an earlier stop in the pumping loop in this particular case we
rework the worker to requeue itself on every requests. Since the worker
is already running prioritized, the scheduling overhad did not have real
impact on the performance.
