bcmasp_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 bcmasp_get_eee() is redundant, and can be removed. This also makes intf->eee.eee_active unnecessary, so remove this and use a local variable where appropriate.
