This hunk removes the setting of the PCI vendor and device IDs
but I can't see where they are set in the new code.

How will the PCI transport's PCI vendor/device/class IDs be
set (a) when a virtio-blk backend is created and separately
plugged into a virtio-pci transport (b) for the legacy
virtio-pci-blk? [ideally the answer to (b) should be "in the
same way as for (a)"]
