The buffer is used for the description provided on the virsh command line:
$ virsh desc <domain> Description

If you don't provide the description:

$ virsh desc --edit <domain>

then 'desc' is NULL and we need to fetch the existing domain description and
let the user edit it. Your patch removes this functionality.
