[alsa-devel] alsa-plugins: pcm_a52.c uses recently removed avcodec_{alloc, free}_frame

[Daniel Kirchner]

pcm_a52.c uses avcodec_alloc_frame and avcodec_free_frame that have
been replaced by av_frame_alloc and av_frame_free in recent versions of
libavcodec. The following patch should fix this while remaining
backwards compatible.
