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.
