vqavideo: return error if image size is not a multiple of block size
The decoder assumes in various places that the image size
is a multiple of the block size, and there is no obvious
way to support odd sizes. Bailing out early if the header
specifies a bad size avoids various errors later on.
Fixes CVE-2012-0947.
