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/. Change-Id: If333c20cf9503f40687ec926c44c7e50222c05b5 BUG: 1544699 Signed-off-by: Anoop C S <anoopcs@redhat.com>
