[PATCH net-next v2 2/6] net: sxgbe: remove eee_enabled/eee_active in sxgbe_get_eee()

[Russell King (Oracle)]

sxgbe_get_eee() sets edata->eee_active and edata->eee_enabled from its
own copy, and then calls 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.

Therefore, setting these members in sxgbe_get_eee() is redundant.
Remove this, and remove the priv->eee_active member which then becomes
a write-only variable.
