core: make compute_cksum function op_version compatible
Problem: commit 5a152a changed the mechansim of computing the
checksum. In heterogeneous cluster, peers are running into
rejected state because we have different cksum computation
mechansims in upgraded and non-upgraded nodes.
Solution: add a check for op-version so that all the nodes
in the cluster follow the same mechanism for computing the
cksum.
