netdev/phy: Use mdiobus_read() so that proper locks are taken.
Accesses to the mdio busses must be done with the mdio_lock to ensure
proper operation. Conveniently we have the helper function
mdiobus_read() to do that for us. Lets use it in get_phy_id() instead
of accessing the bus without the lock held.
