RHEL-9.3.0 will come with qemu 8.0.0 that already includes the fix.

    intel-iommu: fail DEVIOTLB_UNMAP without dt mode
    
    Without dt mode, device IOTLB notifier won't work since guest won't
    send device IOTLB invalidation descriptor in this case. Let's fail
    early instead of misbehaving silently.
