ixgbe: Not allow 8259x unsupported wol options change from ethtool

Wake-on-lan is currently only supported by 82599 KX4 devices, in all
other cases return a proper value from ixgbe_wol_exclusion function call.
Otherwise from ethtool we will be able to change wol options of
unsupported 8259x devices.
