Bjørn Mork 05ffb3e287 usbnet: make usbnet_get_link() fall back to ethtool_op_get_link() ...

Make usbnet_get_link() fall back to ethtool_op_get_link() instead of
defaulting to 1.  
     
This makes usbnet_get_link return valid results without the need for a
driver specific check_connect or mii ops as long as the driver calls
netif_carrier_{on,off}() as appropriate.  cdc_ether is an example of
such a driver.
