Commit a075230e4a0f ("Use ct_mark for masked access to make flows
HW-offloading friendly.") started using the ct_mark.blocked and
ct_mark.ecmp_reply_port ct_label. In usual scenarios this new feature would
be picked up when the next stable release becomes available (i.e., 22.06.0).
However, the commit was also backported to stable branches (branch-22.03 and
branch-21.12).
While the supported upgrade scenario for OVN when moving to a new
stable release is to ensure that ovn-controllers are upgraded first,
it's not really clear that this restriction applies to "z-stream"
upgrades too (e.g., from v21.12.1 to v21.12.2).
Some CMSs, like RHEV (Red Hat Virtualization), expect ovn-controllers
running older code from a stable branch to be able to interpret all
Southbound contents generated by ovn-northd instances built from the
same or newer versions of the stable branch.
Ensure that ct_mark.blocked and ecmp_reply_port are used only when all
chassis registered in the Southbound support it.
