[Ocfs2-devel] [PATCH] Revert "ocfs2: bump up o2cb network protocol version"

[Junxiao Bi]

This reverts commit 38b52efd218bf2a11a5b4a8f56052cee6684cfec.

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 the application like VMs on the
remaining nodes can't be live migrated to the upgraded one. This
will cause an outage. Since negotiate hb timeout behavior didn't
change without this commit, so revert it.
