Revert "ocfs2: bump up o2cb network protocol version"

This reverts commit d5eebd62353e9c1434951436c4d1d8d7a636c17d.

This commit made rolling upgrade fail. When one node is upgraded
to new version with this commit, the remaining nodes will fail to
establish connections to it, then vms on the remaining nodes can't
be live migrated to that node. This will cause an outage.
