Bug Description

This is the same bug as fix-released LP:1853047
We encountered it on 3.2/beta snap, here are artifacts
https://oil-jenkins.canonical.com/artifacts/c61bbcf9-41d8-4898-b165-30923f07562e/index.html

We use 3.2/beta only in one silo because it solves for us a problem with arm64, that is why we hit it only once

This is similar to bug 1853047, but slightly different. In bug 1853047, it was a bug in the code that updated the network interfaces for a controller.

In this case it's Controller.report_neighbours() that is creating the VLAN. It sees that VLAN 2958 is visible, so it creates a VLAN object in the interface fabric.

I'm not sure how to fix this yet, but I'm looking into it still.
