Title:
  TypeError: _delete_nic_metadata() takes exactly 3 arguments (4 given)

Status in OpenStack Compute (nova):
  Fix Released

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

  "Virtual device tagged attach"(*1) has been added in microversion 2.49.
  After attaching the interface by using this function, detaching the interface from the server does not work properly.
  So attaching the interface again fails.

  *1: https://blueprints.launchpad.net/nova/+spec/virt-device-tagged-
  attach-detach

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

  1. attach an interface (neutron port) to a server with tag
  2. detach the interface from the server
     The following message is logged in nova-compute.log.

     TypeError: _delete_nic_metadata() takes exactly 3 arguments (4
  given)

  3. attach the interface (neutron port) to the server again
     HTTP 500 returns.
     <class 'VirtualInterfaceCreateException_Remote'> (HTTP 500) (Request-ID: req-5c369d01-e2f2-4cba-97a9-84fba8e240af)

  Environment
  ===========
  OS: Ubuntu 16.04.2 LTS
  nova: master(commit de5c9e076d5df24a996abf2146fc4c468cf54d71)
