When stopping a video stream the driver waits for ongoing DMA opeations
to complete for the currently active buffer, but doesn't release the
non-active queued buffers. This isn't a problem in most cases as the
video device is usually closed after the stream is stopped, which will
release all the buffers. However the problem would generate a warning
when switching to videobuf2. Fix it by cancelling all buffers after DMA
operations have completed.
