[FFmpeg-cvslog] smacker: remove unnecessary call to avctx->release_buffer in decode_frame()

[Stefano Sabatini]

ffmpeg | branch: master | Stefano Sabatini <stefano.sabatini-lala at poste.it> | Tue Apr 26 11:37:36 2011 +0200| [4f2954e2327c211f3fbe20b84f4881e1f8df1528] | committer: Ronald S. Bultje

smacker: remove unnecessary call to avctx->release_buffer in decode_frame()

The release_buffer was cleaning the provided frame, thus causing the
successive call to avctx->reget_buffer() to allocate a new frame.  In
case the returned frame was not the same one previously returned but a
new one with different data, it resulted in artifacts.
