Fix OOB access in mpeg4/h263 decoder

The decoder does not support an increase in frame width, and
would exceed its buffer if the width increased mid-stream.
There was an existing check to prevent the total frame size
(width*height) from increasing, but in fact the decoder also
does not even support a width increase, even if the height
decreases correspondingly.
