Hardware sync state changes are logged as AUDIT

[Björn Tillenius]

Using MAAS 3.5, and looking at at the event logs, I see a lot of these messages:

       {
            "username": "unknown",
            "node": "fnbpk6",
            "hostname": "ibis",
            "id": 55553,
            "level": "AUDIT",
            "created": "Thu, 18 Apr. 2024 08:30:12",
            "type": "Node PCI Device hardware sync state change",
            "description": "pci device 21 was updated on node fnbpk6"
        },

First of all, we shouldn't log these as AUDIT.

But furthermore, we seem to log a lot of these message, even though nothing has change. See bug 2051988.
