net: mdio-mux: fix unbalanced put_device
mdio_mux_uninit() call put_device (unconditionally) because of of_mdio_find_bus() in mdio_mux_init. But of_mdio_find_bus is only called if mux_bus is empty. If mux_bus is set, mdio_mux_uninit will print a "refcount_t: underflow" trace. This patch add a get_device in the other branch of "if (mux_bus)".
