"of: overlay: add missing of_node_get() in __of_attach_node_sysfs"
added a missing of_node_get() to __of_attach_node_sysfs().  This
results in a refcount imbalance for nodes attached with
dlpar_attach_node().  The calling sequence from dlpar_attach_node()
to __of_attach_node_sysfs() is:

   dlpar_attach_node()
      of_attach_node()
         __of_attach_node_sysfs()
