Fix OpenStackVersion minor update workflow hanging on OVN dataplane check

During a minor update, the OpenStackVersion controller was getting stuck
with incorrect condition states even after deployments completed:
- MinorUpdateOVNDataplane: "in progress" (stuck)
- MinorUpdateControlplane: "not started" (never executed)

Root Cause:
The DataplaneNodesetsOVNControllerImagesMatch function checked
nodeset.IsReady(), which failed when subsequent deployments
(e.g., edpm-update) started running. This caused the function to
return false even though the OVN update deployment (edpm-ovn-update)
had already completed successfully.

The nodeset's overall Ready status was False because edpm-update was
running, blocking the minor update workflow from progressing to the
next steps (RabbitMQ, MariaDB, controlplane services, etc.).

Solution:
Remove the nodeset.IsReady() check from DataplaneNodesetsOVNControllerImagesMatch.
The nodeset's Status.ContainerImages["OvnControllerImage"] is only updated
when a deployment completes successfully (openstackdataplanenodeset_controller.go:598-600).
Therefore, if the OVN image matches the target version, the OVN update
deployment has already completed, regardless of the nodeset's overall Ready status.

Why we can't check deployment-specific conditions:
The nodeset stores deployment conditions in Status.DeploymentStatuses map,
keyed by deployment name (e.g., "edpm-ovn-update"). However, deployment
names are dynamic and not known at this point in the code, making it
impossible to check specific deployment conditions directly.

Note: The final DataplaneNodesetsDeployed check still uses nodeset.IsReady()
because it validates the completion of the entire minor update workflow,
where we do want to ensure the nodeset is fully ready.
