net: phy: fixed_phy: set phy_mask before calling mdiobus_register()

There's no point probing for phys on this artificial bus, so we can
save a little bit of boot time by telling mdiobus_register() not to do
that.

This doesn't have any functional change, since, at this point,
fixed_mdio_read() returns 0xffff for all addresses/registers, so

  mdiobus_scan() -> get_phy_device() -> get_phy_c22_id()

will return -ENODEV, which is just ignored.
