lib: v4l2: Set sizeimage during v4l2_set_format()
videobuf2 relies on the sizeimage field to calculate buffer size when the format is MJPEG, because the bytes-per-line calculation is missing. Fill in that field as part of v4l2_set_format() so the API works correctly. Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Signed-off-by: Daniel Scally <dan.scally@ideasonboard.com>
