6904168c79 avcodec/mjpegdec: Print error in case of CMYK 
Also fail if AV_EF_EXPLODE is set.
We do not fail by default, but rather return some image as it may be usefull to the
end user to see what is on the image, for example text could be read quite fine and
objects recognized.

Possibly fixes Ticket3424

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.
