Currently, no matter whether a node actually has memory or not,
calculate_node_totalpages() is used to account number of pages in
zone/node. However, for node without memory, these unnecessary
calculations can be skipped. All the zone/node page counts can be set to
0 directly. So introduce reset_memoryless_node_totalpages() to perform
this action.
Furthermore, calculate_node_totalpages() only gets called for the node
with memory.
