[media] v4l2: uvcvideo: Allow using larger buffers
A test in uvc_video_decode_isoc() checks whether an image has been received from the camera completely. For this the data amount is compared to the buffer length, which, however, doesn't have to be equal to the image size. Switch to using formats .sizeimage field for an exact expected image size.
