Title:
  Nested loop breaking out doesn't handle correctly

Status in OpenStack Compute (nova):
  In Progress

Bug description:
  https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py#L1674-L1681

  for p in ports:
      for ip in p['fixed_ips']:
          if ip['ip_address'] == address:
              port_id = p['id']
              break

  in the above nested loops, when we find the port_id, it just break one
  for loop, the outside loop will continue, it's a bit waste, should
  handle this gracefully.
