xenpaging: remove domain_id and mfn from struct xenpaging_victim

Remove unused member 'mfn' from struct xenpaging_victim.

xenpaging operates on a single guest, so it needs only a single
domain_id.  Remove domain_id from struct xenpaging_victim and use the
one from paging->mem_event where needed. Its not used in the policy.

This saves 4MB runtime data with a 1GB pagefile.
