There seems to be many modules where ip-address was used
when the intention of the WG was to use ip-address-no-zone.

The easiest solution is to do nothing, and force the server implementers to
deal with it.
A server is obligated to check all client input.
Any request with a zone index can be rejected instead of accepted.
This solution is compatible with the OpenConfig typedef (unless zone index
actually used).
