net: mdio: Delete usage of driver_deferred_probe_check_state()

Now that fw_devlink=on by default and fw_devlink supports interrupt
properties, the execution will never get to the point where
driver_deferred_probe_check_state() is called before the supplier has
probed successfully or before deferred probe timeout has expired.

So, delete the call and replace it with -ENODEV.
