[FFmpeg-cvslog] avcodec/decode: fix warning when decoding pseudo paletted formats

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.
