[Libvirt-cim] [PATCH 4/4] libxkutil: clean entire device structure to avoid memory corruption

[Viktor Mihajlovski]

If cleanup_virt_device is called twice (e.g. during modify resource)
a double free can occur because only the dev substructure has
been memset to zero. Now zeroing the entire structure.
