[FFmpeg-cvslog] avformat/pcmdec: Deduplicate AVClasses

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Mon Jun  7 16:13:33 2021 +0200| [168565ce44308451a50b3ece731727988e0f2389] | committer: Andreas Rheinhardt

avformat/pcmdec: Deduplicate AVClasses

The child_class_next API relied on different (de)muxers to use
different AVClasses; yet this API has been replaced by
child_class_iterate.
