dec_audio: do not overwrite sh_audio->wf->wFormatTag

Browse Source 
No decoder actually used this value (except ad_acm, which was removed a
while ago), so this change shouldn't have any bad consequences.
ad_ffmpeg passes wf to libavcodec decoders, but only the extra data
portion.

This change is needed by the next commit.
