[libvirt] [PATCH] Fix a memory leak in virsh.

[Laine Stump <laine@xxxxxxxxx>]

I found this while looking for examples of using
virNodeDeviceGetXMLDesc(). AFAIK, *all* of the *GetXMLDesc() functions
return a newly allocated chunk of memory that is owned by the caller,
who must free it when they're done...
