af15c17daa avcodec/mjpegdec: remove new flipping code 
It stored images wrong in the user provided buffers (that is you would
end up with a wrongly flipped image if you used direct rendering).
Also it used wrong dimensions as noticed by ubitux

Enable the old code unconditionally so flipping works correctly
again.
