x86/hvm: explicitly mark ioreq server pages dirty

...when they are added back into the guest physmap, when an ioreq
server is disabled. If this is not done then the pages are missed
during migration, causing ioreq server creation to fail on the remote end.

This problem only manifests if the ioreq server is non-default because in
the default case the pages are never removed from the guest physmap.
