[PATCH net-next v2 1/2] net: phy: improve check for when to call phy_resume in mdio_bus_phy_resume

[Heiner Kallweit <hkallweit1@gmail.com>]

We don't have to do all the checks again which we did in
mdio_bus_phy_suspend already. Instead we can simply check whether
the PHY is actually suspended and needs to be resumed.
