Configuration (read) atomicity.
Aka issue VIRTIO-35.
This is solved per transport:
1) PCI: use the 8 bit reserved field.
Assume that if you really change that fast, you'll do it lazily on
config space read.
2) MMIO (already solved by v2 update)
3) CCW: no transport changes.
They always read/write the entire thing. This just shows that
Cornelia is smarter than I am.
