svq1dec: Unbreak the scratch buffer allocation

The input packets are always assumed to be padded and
the av_fast_ family of function takes a pointer to a pointer.

Thanks to Nicolas Dufresne <nicolas.dufresne@collabora.com> for
a similar patch.

Introduced in 7b588bb691644e1b3c168b99accf74248a24e3cf.
