RH-Commit: [1/10] f374aaae221bc5a4c2521a267d21350b812e11ba (lulu6/qemu-kvm3)
https://bugzilla.redhat.com/show_bug.cgi?id=1905805
To support configure interrupt for vhost-vdpa
Introduce VIRTIO_CONFIG_IRQ_IDX -1 as configure interrupt's queue index,
Then we can reuse the functions guest_notifier_mask and guest_notifier_pending.
Add the check of queue index in these drivers, if the driver does not support
configure interrupt, the function will just return
