During vfio-pci open_device, pass the KVM associated with the vfio group (if one exists). This is needed in order to pass a special indicator (GISA) to firmware to allow zPCI interpretation facilities to be used for only the specific KVM associated with the vfio-pci device. During vfio-pci close_device, unregister the notifier.
