Subject: [PATCH] examples: check asprintf return value in client_info.c

On error, asprintf returns -1 and the contents of the string
pointer is undefined. In the rest of the libvirt code,
the virAsprintf wrapper takes care of that.

Check the return value and report a generic error, since we
purposefully avoid linking to virutil.
