I am not sure these new values are correct, not am I sure

use of them but they caused a lot of confusion, but this
seems to make things closer to matching the documentation.

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.
