[ethtool] ethtool: --set-eee sends ETHTOOL_SEEE ioctl even if nothing changed

From: Bruce Allan <redacted>

When setting EEE parameters with the --set-eee command line option,
ethtool will send the ETHTOOL_SEEE ioctl down to the driver even if
none of the provided parameters are a change from current settings.
Simply ignore it when that happens as done with other ethtool commands.
