igc: Fix Energy Efficient Ethernet support declaration
The commit 01cf893bf0f4 ("net: intel: i40e/igc: Remove setting Autoneg in
EEE capabilities") removed SUPPORTED_Autoneg field but left inappropriate
ethtool_keee structure initialization. When "ethtool --show <device>"
(get_eee) invoke, the 'ethtool_keee' structure was accidentally overridden.
Remove the 'ethtool_keee' overriding and add EEE declaration as per IEEE
specification that allows reporting Energy Efficient Ethernet capabilities.
Examples:
Before fix:
ethtool --show-eee enp174s0
EEE settings for enp174s0:
EEE status: not supported
After fix:
EEE settings for enp174s0:
EEE status: disabled
Tx LPI: disabled
Supported EEE link modes: 100baseT/Full
1000baseT/Full
2500baseT/Full
Fixes: 01cf893bf0f4 ("net: intel: i40e/igc: Remove setting Autoneg in EEE capabilities")
