xen: arm: fix is_xen_fixed_mfn
The current implementation is nonsense since the xenheap and the xen text/data/etc mappings are nowhere near each other. This is only actually used by the page offlining code, which isn't active on ARM. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
