    Delete non tag related device metadata during detach
    
    When the blueprint virt-device-tagged-attach-detach [1] was
    implemented the metadata cleanup during interface detach made an
    assumption that metadata only exists if the detached vif has tags.
    However metadata exists for vif with vlan information as well. In such
    case the metadata is leaked during interface detach. This patch removes
    this assumption from the detach code path.

Title:
  interface metadata is not regenerated after interface detach

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  If a tagged interface is detached from an instance the device metadata
  is not regenerated and therefore the detached interface still visible
  to the guest via the metadata service.

  When the blueprint virt-device-tagged-attach-detach was implemented
  the metadata handing was missed in the detach code path
