Bug description:
  Description
  ===========

  I7eb86edc130d186a66c04b229d46347ec5c0b625 introduced support for the
  libvirt hot unplug error code VIR_ERR_DEVICE_MISSING that was itself
  introduced in libvirt v4.1.0. The change did not however cover
  versions < v4.1.0 such as v4.0.0 installed in our bionic based CI test
  envs, causing attribute errors when we attempt to reference.

  Steps to reproduce
  ==================

  * Attempt to detach a busy or missing device from an instance with
  libvirt < v4.1.0 installed.

  Expected result
  ===============
  The correct error codes are referenced and checked to confirm what happened.

  Actual result
  =============
  AttributeError: module 'libvirt' has no attribute 'VIR_ERR_DEVICE_MISSING' as the error code is not available prior to libvirt v4.1.0.

  Environment
  ===========
  1. Exact version of OpenStack you are running. See the following
    list for all releases: http://docs.openstack.org/releases/

     master

  2. Which hypervisor did you use?
     (For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)
     What's the version of that?

     libvirt + *

  2. Which storage type did you use?
     (For example: Ceph, LVM, GPFS, ...)
     What's the version of that?

     N/A

  3. Which networking type did you use?
     (For example: nova-network, Neutron with OpenVSwitch, ...)

     N/A
