bootmem: Use for_each_mem_pfn_range() in page_alloc.c
The previous patch added for_each_mem_pfn_range() which is more versatile than for_each_active_range_index_in_nid(). This patch replaces for_each_active_range_index_in_nid() and open coded early_node_map[] walks with for_each_mem_pfn_range(). All conversions in this patch are straight-forward and shouldn't cause any functional difference. After the conversions, for_each_active_range_index_in_nid() doesn't have any user left and is removed.
