[libvirt] [PATCH v3 10/36] network: move fixup for domain actual net def out of network driver
The hypervisor drivers are soon going to communicate with the network
driver via public APIs only. As such the network driver will not ever
see the domain actual network def. Thus the backwards compatibility
fixup logic must be moved out of the network driver.
