[PATCH] mm/page_alloc: make alloc_node_mem_map() __init rather than __ref

From: Mike Rapoport <rppt@linux.ibm.com>

alloc_node_mem_map() is never only called from free_area_init_node() that
is an __init function.

Make the actual alloc_node_mem_map() also __init and its stub version
static inline.
