Michael Niedermayer 8fbe1f634f avcodec/libfdk-aacdec: Correct buffer_size parameter ...

the timeDataSize argument to aacDecoder_DecodeFrame() seems undocumented and until
2016 04 (203e3f28fbebec7011342017fafc2a0bda0ce530) unused.
after that commit libfdk-aacdec interprets it as size in sample units and memsets that on error.
FFmpeg as well as others (like GStreamer) did interpret it as size in bytes

Fixes: 1442/clusterfuzz-testcase-minimized-4540199973421056 (This requires recent libfdk to reproduce)
