The slot info comes from the serial number "hpdev->desc.ser", which may not guarantee
uniqueness: "...Hyper-V doesn't provide unique serial numbers": see the changelog of the below

And we can pass through multiple devices to a VM in any order (i.e. hot add/remove), so IMO
the "slot" info is not unique and persistent.
