dfb9a3f7f3 avcodec/utils: don't return negative values in av_get_audio_frame_duration() 
In some extrme cases, like with adpcm_ms samples with an extremely high channel
count, get_audio_frame_duration() may return a negative frame duration value.
Don't propagate it, and instead return 0, signaling that a duration could not
be determined.

Fixes ticket #9312
