virtio-pci: don't try to mask or unmask vqs without notifiers
We should validate the vq index against nvqs_with_notifiers. Otherwise we may
try to mask or unmask vector for vqs without notifiers (e.g control vq). This
will lead qemu abort on kvm_irqchip_commit_routes() when trying to boot win8.1
guest.
Fixes 851c2a75a6e80c8aa5e713864d98cfb512e7229b ("virtio-pci: speedup MSI-X
masking and unmasking")
