protocol/server: Insert dummy clnt-lk-version to avoid upgrade failure
This is required as we check for 'clnt-lk-version' in SETVOLUME callback
with older clients in place against newer servers. Change is similar to
what we have done via https://review.gluster.org/#/c/19560/.
(cherry picked from commit fecb0fc748806d4e6d61bcbef976acf473e55c82)
