ffmpeg | branch: master | Steven Liu <lq at chinaffmpeg.org> | Fri Jun 24 13:55:41 2022 +0800| [7c05b7951cb47716230c95744240bc60ec5f9433] | committer: Steven Liu

avcodec/audiotoolboxenc: return external error if encode failed

because the AudioConverterFillComplexBuffer can return 0 or 1 if
success.
so set the ret to 0 it AudioConverterFillComplexBuffer success and
return ret value for success or return AVERROR_EXTERNAL when
AudioConverterFillComplexBuffer failed.
BTW change the error message log level from warning to error.
