page_alloc: use N_MEMORY instead N_HIGH_MEMORY change the node_states initialization
N_HIGH_MEMORY stands for the nodes that has normal or high memory. N_MEMORY stands for the nodes that has any memory. The code here need to handle with the nodes which have memory, we should use N_MEMORY instead. Since we introduced N_MEMORY, we update the initialization of node_states.
