Michael Grzeschik 52a39f2cf6 usb: gadget: uvc: cleanup request when not in correct state 
The uvc_video_enable function of the uvc-gadget driver is dequeing and
immediately deallocs all requests on its disable codepath. This is not
save since the dequeue function is async and does not ensure that the
requests are left unlinked in the controller driver.

By adding the ep_free_request into the completion path of the requests
we ensure that the request will be properly deallocated.
