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 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit 327a968817a366c24d1513526258a3dbbcf888a7) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
