[Bug 1641814] [NEW] Don't apply multi-queue to SRIOV ports

Public bug reported:

The multi-queue feature was added:
https://blueprints.launchpad.net/nova/+spec/libvirt-virtio-net-multiqueue
and it is controlled using image metadata: hw_vif_mutliqueue_enabled=true|false
when it is set to be true, the related xml config will be handled:
http://git.openstack.org/cgit/openstack/nova/tree/nova/virt/libvirt/vif.py#n130

when users want to launch an instance with a SRIOV port and several normal ports
with multi-queue feature, ERROR can take place due to wrong driver name for SRIOV
interface:

Bug description:
  The multi-queue feature was added:
  https://blueprints.launchpad.net/nova/+spec/libvirt-virtio-net-multiqueue
  and it is controlled using image metadata: hw_vif_mutliqueue_enabled=true|false
  when it is set to be true, the related xml config will be handled:
  http://git.openstack.org/cgit/openstack/nova/tree/nova/virt/libvirt/vif.py#n130

  when users want to launch an instance with a SRIOV port and several normal ports
  with multi-queue feature, ERROR can take place due to wrong driver name for SRIOV
