passthrough: allow pass-through devices to share virtual GSI
Allow multiple pass-through devices to use the same guest_gsi.
The motivation for this is:
* Allow multi-function devices to be passed through as multi-function
devices
* Allow more than two pass-through devices.
- This will place more contention on the GSI-space, and allocation
becomes a lot simpler if GSI sharing is allowed.
