ixgbe: Correctly report Wake On LAN for 82599 KX4 devices

ethtool isn't reporting the support level of WoL for 82599 KX4 devices.
While the device does support WoL, ethtool was never updated to properly
report the level of support, nor will it allow ethtool to modify the type
of packets to listen for.
