Do not allow uvch264src to kill pipeline on missed MJPEG segment...

It appears that the Logitech C920 sometimes drops the next to last segment of
RAW aux data contained within the MJPEG container.  H264 data that is
multiplexed with in the same container does not appear to be affected.  This
appears to be a bug in the Logitech C920 firmware and uvch264src should not
flag and error killing the pipeline...see the attached patch...sometimes it can
take 24 hours of continuous streaming for the problem to occur, but sometimes
it can take only a couple of hours.
