lib/neutron-legacy: replace ip when re-stacking

Replicated Yi Zhao's fix for re-adding ipv6 addresses to neutron-legacy
(review I9ff62023dbc29a88aec3c48af331c0a49a1270bb).
Previously, re-stacking failed with "File exists" for ipv6 addresses
on br-ex.  With this change, the existing address is replaced on
br-ex with the appropriate address.
