Fix IidCodec broken by new yangtools
There are multiple versions of network-topology loaded
and yangtools can't tell which one to use. It has ramifications
beyond just OVSDB, but this fixes functionality issues in
OVSDB.
Root issue is two different files with different versions
bundled together. It may not have been issue earlier but is now.
