During memory hotplug testing, I got the following warning:


ERROR: Bad of_node_put() on /memory@0

of_node_release
kref_put
of_node_put
of_find_node_by_type
hot_add_node_scn_to_nid
hot_add_scn_to_nid
memory_add_physaddr_to_nid
...


of_find_node_by_type() loop does of_node_put for us so remove the
duplicate one inside the loop.
