Before Patch:
# virsh pool-destroy poolhba_name
error: Failed to destroy pool poolhba_name
error: internal error: Invalid adapter name 'pci_000x_0x_00_x' for SCSI pool

# virsh nodedev-dumpxml scsi_host2
<device>
  <name>scsi_host2</name>
  <path>xxxx</path>
  <parent>pci_000x_0x_00_x</parent>
  <capability type='scsi_host'>
    <host>2</host>
    ...
    ...
    <capability type='vport_ops'>
      <max_vports>255</max_vports>
      <vports>0</vports>
    </capability>
  </capability>
