powerpc/numa: Remove double of_node_put in hot_add_node_scn_to_nid
commit 6083184269fd723affca4f6340e491950267622a upstream.
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 the of_node_put for us so we only
need the handle the case where we terminate the loop early.
As suggested by Stephen Rothwell we can do the of_node_put
unconditionally outside of the loop since of_node_put handles a
NULL argument fine.
