mm: fix memory hotplug oops from ZONE_MOVABLE changes.
zone_movable_pfn is presently marked as __initdata and referenced from
adjust_zone_range_for_zone_movable(), which in turn is referenced by
zone_spanned_pages_in_node(). Both of these are __meminit annotated. When
memory hotplug is enabled, this will oops on a hot-add, due to
zone_movable_pfn having been freed.
__meminitdata annotation gives the desired behaviour.
This will only impact platforms that enable both memory hotplug
and ARCH_POPULATES_NODE_MAP.
