igb: Use device_set_wakeup_enable

commit e1b86d8479f90aadee57a3d07d8e61c815c202d9 upstream.

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
igb_set_wol().  Accordingly, use device_can_wakeup() for checking
if wake-up is supported by the device.
