Subject: iommu/of: Delete usage of driver_deferred_probe_check_state()
Git-commit: b09796d528bbf06e3e10a4a8f78038719da7ebc6
Patch-mainline: v6.0-rc1
References: bsc#1205701

Now that fw_devlink=on and fw_devlink.strict=1 by default and fw_devlink
supports iommu DT 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.
