Title:
  l2-population with linuxbridge  : recreating a VM with the same ip
  fails

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron havana series:
  Fix Released

Bug description:
  I run in multi node setup with ML2, L2-population and Linuxbridge MD,
  and vxlan TypeDriver.

  I create a VM with ip 10.0.0.105 and mac 00:00:00:55:55:55

  neighbouring table on network node :
  # ip neigh show
  10.0.0.105 dev vxlan-1001 lladdr 00:00:00:55:55:55 PERMANENT

  I delete it.

  neighbouring table on network node :
  # ip neigh show
  10.0.0.105 dev vxlan-1001  FAILED

  I recreate a VM with the same ip/mac :

  neighbouring table on network node :
  # ip neigh show
  10.0.0.105 dev vxlan-1001  FAILED

  in q-agt.log, we can see that the "ip neigh add" command fails.
