cpu-hotplug,memory-hotplug: clear cpu_to_node() when offlining the node
When the node is offlined, there is no memory/cpu on the node. If a
sleep task runs on a cpu of this node, it will be migrated to the cpu on
the other node. So we can clear cpu-to-node mapping.
[akpm@linux-foundation.org: numa_clear_node() and numa_set_node() can no longer be __cpuinit]
