mem_topology_setup() intersects node_possible_map with node_online_map.
Nothing sets node_possible_map before this, so it is NODE_MASK_ALL and
the result is just node_online_map.

In preparation for changing node_possible_map's initial value,
mem_topology_setup() no longer depends on it.

No functional change.
