Subject: mm: use early_pfn_to_nid in register_page_bootmem_info_node

register_page_bootmem_info_node() is invoked in mem_init(), so it will be
called before page_alloc_init_late() if CONFIG_DEFERRED_STRUCT_PAGE_INIT
is enabled.  But, pfn_to_nid() depends on memmap which won't be fully
setup until page_alloc_init_late() is done, so replace pfn_to_nid() by
early_pfn_to_nid().
