domain_conf: Allow to look up virtio-block devices by their CCW address
On s390x, devices are accessed via the channel subsystem by default, so we need to look up the devices via their CCW address there instead of using PCI. This fixes "virsh domfsinfo" on s390x for virtio-block devices (the first attempt from commitf8333b3b0a
did it in the wrong way, reporting the device name on the guest side instead of the target name on the host side). Fixes:f8333b3b0a
("qemu: Fix domfsinfo for non-PCI device information ...")
