media: uvcvideo: Only save async fh if success
commit d9fecd096f67a4469536e040a8a10bbfb665918b upstream. Now we keep a reference to the active fh for any call to uvc_ctrl_set, regardless if it is an actual set or if it is a just a try or if the device refused the operation. We should only keep the file handle if the device actually accepted applying the operation.
