      Description of problem:
      When reboot or shutdown the VM with an Intel iommu device and PF/VF, the qemu-kvm throws the error info like : Fail to lookup the translated address fff22000

      Version-Release number of selected component (if applicable):
      5.14.0-348.el9.x86_64
      qemu-kvm-8.0.0-9.el9.x86_64
      libvirt-9.5.0-5.el9.x86_64
      edk2-ovmf-20230524-2.el9.noarch

      How reproducible:
      100%

      Steps to Reproduce:
      1. import a VM which has intel iommu + virtio-net vhost interface

      # virt-install --machine=q35 --noreboot --name=rhel93 --memory=4096 --vcpus=4 --graphics type=vnc,port=5993,listen=0.0.0.0 --osinfo detect=on,require=off --check all=off --memtune hard_limit=12582912 --memballoon virtio,driver.iommu=on,driver.ats=on --import --noautoconsole --check all=off --network bridge=switch,model=virtio,mac=52:54:00:03:93:93,driver.iommu=on,driver.ats=on --disk path=/home/images/RHEL93.qcow2,bus=virtio,cache=none,format=qcow2,io=threads,size=20,driver.iommu=on,driver.ats=on --features ioapic.driver=qemu --iommu model=intel,driver.intremap=on,driver.caching_mode=on,driver.iotlb=on --boot=uefi --hostdev pci_0000_3b_0e_0  --hostdev pci_0000_3b_0e_1 
      

      2. make sure the VM kernel has enabled intel_iommu=on option

      3. start a VM

      # virsh start rhel93
      

      4. reboot or shutdown the VM
      run "reboot" or "shutdown -h now" in the VM

      5. repeated the step 2 for 5 times

      Actual results:
      The qemu-kvm throws the error info like : Fail to lookup the translated address fff22000

      Expected results:
      The qemu-kvm does not throw any error

      Additional info:
      (1) The cmd I used to reproduce this issue via auto tests:

      # python3 /home/private_autocase/vfio/vfio_sriov_test.py --feature=vf --domain=rhel93 --device_name=MT2892  --machine_type=q35 --bios=ovmf  --test_list="intel_iommu_test"
      or
      # python3 /home/private_autocase/vfio/vfio_sriov_test.py --feature=pf --domain=rhel93 --device_name=82599ES --machine_type=q35 --bios=ovmf  --test_list="intel_iommu_test"
