avcodec/pcm: Remove always-false check

Browse Source 
All codecs here have a valid sample size at this point.
This check has (presumably) been added for DVD PCM,
but even for them the check was always-true after
381e195b46 (and the DVD
code was later moved out altogether). So just remove
this check and the leftover DVD comment.
