mm: make free_area_init_node aware of memory less nodes 

free_area_init_node is also called from memory less node initialization
path (free_area_init_memoryless_node).  It doesn't really make much sense
to display the physical memory range for those nodes: Initmem setup node
XX [mem 0x0000000000000000-0x0000000000000000]

Instead be explicit that the node is memoryless: Initmem setup node XX as
memoryless
