Actually we know idlist != NULL at that point, so the test is not needed.

I wonder if there isn't a bug there actually, if (!found) we should
not get the domain path, it's at least non-optimal. I moved the test
just after the loop where found is set and before xs_get_domain_path()
Actually upon further looking, path is never used. It used to be stored in
the domain IIRC, but here we look for the value and never use it, it just
got freed, so I'm cleaning up that part !
