[FFmpeg-cvslog] avcodec/wma(dec|enc): Fix memleaks upon allocation error

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Thu May  6 16:56:19 2021 +0200| [fcdb012a100b245890949b2d53cb7f042380787d] | committer: Andreas Rheinhardt

avcodec/wma(dec|enc): Fix memleaks upon allocation error

ff_wma_init() can fail without freeing everything it has allocated;
so add the FF_CODEC_CAP_INIT_CLEANUP to the codecs using it.
