Prevent OOB write in soft_avc encoder

Soft avc encoder cached buffer sizes across a point where the sizes
could be reset by an app, allowing crafted requests to hit outside
of the current buffer. This remedies that by forcing buffer reallocation
with new sizes whenever the encoder state at such 'reset' points.
