memcg: fix node_state handling

This should be N_NORMAL_MEMORY.

N_NORMAL_MEMORY is "true" if a node has memory for the kernel.  N_HIGH_MEMORY
is "true" if a node has memory for HIGHMEM.  (If CONFIG_HIGHMEM=n, always
"true")

This check is used for testing whether we can use kmalloc_node() on a node.
Then, if there is a node which only contains HIGHMEM, the system will call
kmalloc_node() which doesn't contain memory for the kernel.  If it happens
under SLUB, the kernel will panic.  I think this only happens on x86_32-numa.
