memory-hotplug: suppress "Device nodeX does not have a release() function" warning
When calling unregister_node(), the function shows following message at
device_release().
"Device 'node2' does not have a release() function, it is broken and must
be fixed."
The reason is node's device struct does not have a release() function.
So the patch registers node_device_release() to the device's release()
function for suppressing the warning message. Additionally, the patch
adds memset() to initialize a node struct into register_node(). Because
the node struct is part of node_devices[] array and it cannot be freed by
node_device_release(). So if system reuses the node struct, it has a
garbage.
