[FFmpeg-devel] [PATCH 6/9] avcodec/libvpxenc: Cleanup on error

[Michael Niedermayer]

This or fifo needs to be freed on errors explicitly
I have not verified that its always safe to call vpx_free() this needs to be checked before applying this

Fixes: memleak
Fixes: 68937/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_LIBVPX_VP8_fuzzer-4830831016214528
