xen: Simplify the space of spaces supported by XENMEM_add_to_physmap(_range)
XENMAPSPACE_gmfn_foreign is not supported by XENMEM_add_to_physmap.
Although in theory XENMEM_add_to_physmap_range could support
XENMAPSPACE_gmfn_range this is no different to
XENMAPSPACE_gmfn in the context of the ranged hypercall so disallow it
to avoid any confusion.
