dns: fix selecting neg. cname entry
- do not select a neg. cache cname entry as a response, unless
the request is for a cname.
This fixes an unlikely bug: someone makes a specific cname
request (from ser) for a name that doesn't resolve and then later when
a normal non-cname request is made (e.g. A) the empty negative cname
entry is selected, leading to a coredump. So far there is no
code in ser that could trigger this bug. Only dns.lookup cname
... from sip-router could trigger it.
