OCPBUGS-65712: Fix instance deletion order

[mandre]

Delete the OpenStack instance before deleting its network ports. This prevents "Policy doesn't allow compute:detach primary port" errors that occur when attempting to delete a primary NIC while the instance still exists.

Deleting the instance automatically detaches all interfaces, so the explicit detach call is no longer needed.
