pipeline: raspberrypi: Fix erroneous bayer buffer requeue on buffer matching
With the recent change in the bayer/embedded buffer matching code, a condition would make the bayer buffer be requeued back to the device, even though it could potentially be queued for matching. This would cause unnecessary frame drops as sync would be lost. The fix is to ensure the bayer buffer only gets requeued if the embedded data buffer queue is not empty, i.e. the buffer truly is orphaned. Additionally, we do this test before deciding to flush any of the two queues of all their buffers.
