It was never meant to do otherwise, as av_packet_get_side_data() returns the first
entry it finds of a given type.

fc63d5ceb3 Merge commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a' 
* commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a':
  theora: export cropping information instead of handling it internally
  h264dec: export cropping information instead of handling it internally
  h264dec: be more explicit in handling container cropping
  hevcdec: export cropping information instead of handling it internally

This commit is a noop.

This changes the cropping behavior, when it's supposedly only meant to move
it outside of the decoder.
See https://ffmpeg.org/pipermail/ffmpeg-devel/2017-May/211239.html for the
discussion about it.
