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.
