mm: Move early_node_map[] reverse scan helpers under HAVE_MEMBLOCK
Heiko found recent memblock change triggers these warnings on s390:
mm/page_alloc.c:3623:22: warning: 'last_active_region_index_in_nid' defined but not used
mm/page_alloc.c:3638:22: warning: 'previous_active_region_index_in_nid' defined but not used
Need to move those two function under HAVE_MEMBLOCK with its only
user, find_memory_core_early().
-tj: Minor updates to description.
