e1000e: Use device_set_wakeup_enable

Browse Source 
Since dev->power.should_wakeup bit is used by the PCI core to
decide whether the device should wake up the system from sleep
states, set/unset this bit whenever WOL is enabled/disabled using
e1000_set_wol().  Accordingly, use device_can_wakeup() for checking
if wake-up is supported by the device.
