net: txgbe: corrige la advertencia de aserción RTNL al eliminar el módulo

Para la NIC de cobre con PHY externo, el controlador llamó a
phylink_connect_phy() durante la sonda y phylink_disconnect_phy() durante
la eliminación. Esto causó una advertencia de aserción RTNL en phylink_disconnect_phy()
al eliminar el módulo.

Para solucionar esto, añada rtnl_lock() y rtnl_unlock() alrededor de
phylink_disconnect_phy() en la función de eliminación.
