offload: Do diff collection later

Browse Source 
We were collecting diffs based on the can_offload/can_raise
information, but attaching the texture to the subsurface can
fail (e.g. if its not a dmabuf texture), in which case can_offload
turned out to be wrong. So move the diff collection to the end
and do it based on the whether we actually succeeded in attaching
the texture.
