[PATCH net] net: phy: fix aneg restart in phy_ethtool_set_eee

[Heiner Kallweit]

phy_restart_aneg() enables aneg in the PHY. That's not what we want
if phydev->autoneg is disabled. In this case still update EEE
advertisement register, but don't enable aneg and don't trigger an
aneg restart.

Fixes: f75abeb8338e ("net: phy: restart phy autonegotiation after EEE 
advertisment change")
