[Bug 1410688] [NEW] Router interface should not be updated to have more ips

 

Public bug reported:

When adding an interface to a router with a port, Neutron will check,
and if that port has more than one fixed ips, Neutron will reject that
request. However, we can still update a router port to have more than
one fixed ips.
