[wm4]

ffmpeg | branch: master | wm4 <nfxjfg at googlemail.com> | Wed Apr  4 18:07:03 2018 +0200| [709e0291d659d089527ec7c048f9b2608183df64] | committer: wm4

avcodec/decode: fix warning when decoding pseudo paletted formats

The pseudo palette allocation is optional now. But if it's still
allocated (like the internal get_buffer2 implementation does, for
compatibility), it shouldn't print a warning.
