avformat/nutdec: Don't shrink packet size manually

It is unnecessary because an av_shrink_packet() a few lines below
will set the size; furthermore, it is actually harmful, because
av_shrink_packet() does nothing in case the size already matches,
so that the packet's padding is not correctly zeroed.
