Michael Niedermayer e2def5f382 avcodec/cngdec: Remove AV_CODEC_CAP_DELAY 
As is the decoder will never stop, it will cause an infinite loop. The RFC seems only
to speak of non empty packets so endlessly generating noise from the last empty flush
packets seems wrong.

Fixes: infinite loop
Fixes: 18333/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_COMFORTNOISE_fuzzer-5668481831272448
