When a new video frame is started, the driver takes the next video buffer from
the list of active buffers and moves it to dev->usb_ctl.vid_buf / dev->usb_ctl.vbi_buf
for further processing.

On streaming stop we currently only give back the pending buffers from the list
but not the ones which are currently processed.

This causes the following warning from the vb2 core since kernel 3.15:
