[PATCH 2/2] e1000e: Make WOL info in ethtool consistent with device wake up ability

[Chen Yu]

Currently the ethtool shows that WOL(Wake On Lan) is enabled
even if the device wakeup ability has been disabled via sysfs:
  cat /sys/devices/pci0000:00/0000:00:1f.6/power/wakeup
   disabled

  ethtool eno1
  ...
  Wake-on: g

Fix this in ethtool to check if the user has explicitly disabled the
wake up ability for this device.
