ML2 RPC port_update method causes the error message.
ML2 RPC base version is wrongly bumped to 1.1 and it breaks hyper-v agent with ML2 plugin.
It is not an intended behavior.
Ideally ML2 RPC API base version should be reverted to 1.0, but it affects several agents,
so bumping API version in hyper-v agent sounds reasonable approach.
