net: mdio: fix owner field for mdio buses registered using device-tree

[ Upstream commit 99669259f3361d759219811e670b7e0742668556 ]

Bus ownership is wrong when using of_mdiobus_register() to register an mdio
bus. That function is not inline, so when it calls mdiobus_register() the wrong
THIS_MODULE value is captured.
