protcol/client: Insert dummy clnt-lk-version to avoid upgrade failure
With being merged, we no longer send client's lk-version to server side and the corresponding check on server is also removed. But when clients are upgraded prior to servers, the check for lk-version at server side fails and is reported back to clients resulting in disconnection. Since we don't have lock-recovery (lk-version and grace-timeout) logic anymore in code base our best bet would be to add client's default lk-version i.e, 1, into the dictionary just to make server side check pass and continue with remaining SETVOLUME operations.
