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.

4xm: use reget_buffer() in decode_frame()

Also remove unnecessary call to avctx->release_buffer(). reget_buffer
is required since apparently the codec needs to be feeded with the
previous frame data.
Releasing the frame and using get_buffer was working only in the case
get_buffer() was returning the old frame data, and resulting in
playback artifacts otherwise.
