As for commit 68baf692c435 ("powerpc/pseries: Fix of_node_put()
underflow during DLPAR remove"), the call to of_node_put()
must be removed from pSeries_reconfig_remove_node().

dlpar_detach_node() and pSeries_reconfig_remove_node() call
of_detach_node(), and thus the node should not be released
in this case too.
