The final result seems fine. It just seems it would be nice to have tests
against regressions for LP: #1816106 ("4.15.0-1037 does not see all PCI devices
on GPU VMs").

Yes. That was tested. The fix that was reverted was basically a
hack. The proper solution is introduced by "PCI: hv: Detect and fix
Hyper-V PCI domain number collision"
