net: stmmac: remove eee_enabled/eee_active in stmmac_ethtool_op_get_eee()

Browse source

stmmac_ethtool_op_get_eee() sets both eee_enabled and eee_active, and
then goes on to call phylink_ethtool_get_eee().

phylink_ethtool_get_eee() will return -EOPNOTSUPP if there is no PHY
present, otherwise calling phy_ethtool_get_eee() which in turn will call
genphy_c45_ethtool_get_eee().

genphy_c45_ethtool_get_eee() will overwrite eee_enabled and eee_active
with its own interpretation from the PHYs settings and negotiation
result.

Thus, when there is no PHY, stmmac_ethtool_op_get_eee() will fail with
-EOPNOTSUPP, meaning eee_enabled and eee_active will not be returned to
userspace. When there is a PHY, eee_enabled and eee_active will be
overwritten by phylib, making the setting of these members in
stmmac_ethtool_op_get_eee() entirely unnecessary.

Remove this code, thus simplifying stmmac_ethtool_op_get_eee().
