After slave_data->phy_node is assigned (via of_node_get or

  releases the loop's port_np reference but not the phy_node reference.
  This causes a device_node reference leak.

Release slave_data->phy_node via of_node_put before jumping to
  err_node_put on error paths after phy_node has been acquired.
