qemuAgentFSInfoToPublic() currently only sets the devAlias for PCI devices. However, the QEMU guest agent could also provide the device name in the "dev" field of the response for other devices instead (well, at least after fixing another problem in the current QEMU guest agent...). So if creating the devAlias from the PCI information failed, let's fall back to the name provided by the guest agent. This helps to fix the empty "Target" fields that occur when running "virsh domfsinfo" on s390x where CCW devices are used for the guest instead of PCI devices. Also add a proper debug message here in case we completely failed to set the device alias, since this problem here was very hard to debug: The only two error messages that I've seen were "Unable to get filesystem information" and "Unable to encode message payload" - which only indicates that something went wrong in the RPC call. No debug message indicated the real problem, so I had to learn the hard way why the RPC call failed (it apparently does not like devAlias left to be NULL) and where the real problem comes from.

==============================
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
Further information about the libvirt project can be found on the
website:
