[PATCH 1/3] exa/mixed: avoid copying back pixmap data when no migration took place

- When the driver handles the prepare access no copying is needed.
- Delayed pixmap creation should be fine, because it's handled by the
first prepare access, but the exaPixmapIsOffscreen check in finish access
will return FALSE without a driver pixmap.
