Dr. David Alan Gilbert bad9c5a516 virtio-rng-pci: fix migration compat for vectors
Fixup the migration compatibility for existing machine types
so that they do not enable msi-x.

Symptom:

(qemu) qemu: get_pci_config_device: Bad config data: i=0x34 read: 84 device: 98 cmask: ff wmask: 0 w1cmask:0
qemu: Failed to load PCIDevice:config
qemu: Failed to load virtio-rng:virtio
qemu: error while loading state for instance 0x0 of device '0000:00:03.0/virtio-rng'
qemu: load of migration failed: Invalid argument

Note: This fix will break migration from 7.2->7.2-fixed with this patch
