Title:
  Cisco Nexus plugin issue delete_vlan netconf call 2 times in batch
  instance delete

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  Cisco Nexus plugin will issue netconf call delete_vlan to switch when
  the last instance on a tenant network is deleted. In my case I delete
  8 instances in batch, the last instance always failed to be deleted.
  From /var/log/neutron/server.log, Cisco Nexus plugin thrown exception
  "None of the VLANs exist". After study the same log, I found the
  delete_vlan netconf call has been issued 2 times. I expect only 1st
  call is issue, which delete the VLAN on switch. The 2nd call causes
  "None of the VLANs exist".
