Boris Fiuczynski 19b088cfb9 nodedev: fix internal error when no defined mdevs exist
Commit e9b534905f4 introduced an error when parsing an empty list
returned from mdevctl.

This occurs e.g. if nodedev-undefine is used to undefine the last
defined mdev which causes the following error messages

 libvirtd[33143]: internal error: Unexpected format for mdevctl response
 libvirtd[33143]: internal error: failed to query mdevs from mdevctl:
 libvirtd[33143]: mdevctl failed to updated mediated devices

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.
