protcol/client: Insert dummy clnt-lk-version to avoid upgrade failure
With https://review.gluster.org/#/c/12363/ 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.
