Public bug reported:

While updating a FIP without port or fixed ip changed. For example,
updating its description via neutron API, or associate same floatingip
and fixed ip more than once, it will delete the old one ,than add a new
one[0]. It will make network flap.

Because we don't change fip and fiexd ip , so we don't need to do update
in NBDB table, and the network flap should be avoided.
