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. Signed-off-by: David Daney <david.daney@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
