[PATCH v2] V4L2VideoDevice: Call FrameBuffer::Private::cancel() in streamOff()

[Harvey Yang]

At the moment `V4L2VideoDevice::streamOff()` sets
`FrameBuffer::Private`'s metadata directly, while that's equivalent to
calling `FrameBuffer::Private::cancel()`. To ease code tracing, this
patch replace the manual modification with the function call.
