v4l2: populate video_buffer mem field at dequeue
Our v4l2_queue_buffer and v4l2_dequeue_buffer functions give us a wrapper around the raw V4L2 ioctls with a wrapper struct video_buffer around the raw struct v4l2_buffer. The problem is that the video_buffer's mem field is never populated, so there's no way to access the mem that the buffer refers to given only the buffer. Populate the video_buffer's mem field at v4l2_dequeue_buffer based on the dequeued v4l2 buf's index.
