x86/xen: do not use _PAGE_IOMAP in xen_remap_domain_mfn_range()
_PAGE_IOMAP is used in xen_remap_domain_mfn_range() to prevent the pfn_pte() call in remap_area_mfn_pte_fn() from using the p2m to translate the MFN. If mfn_pte() is used instead, the p2m look up is avoided and the use of _PAGE_IOMAP is no longer needed.
