FROMGIT: usb: gadget: uvc: wake pump everytime we update the free list

Since the req_free list will updated if enqueuing one request was not
possible it will be added back to the free list. With every available
free request in the queue it is a valid case for the pump worker to use
it and continue the pending bufferdata into requests for the req_ready
list.
