Log message:
Check for errors returned by _asr_unpack_{header,query,rr}
dname_expand() is the main parsing function for DNS labels. Its errors
are propagated via unpack_dname() to _asr_unpack_query() and
_asr_unpack_rr().
Those two functions would also propagate the errors, but they were
then ignored by the callers which would continue parsing invalid DNS
data.
_asr_unpack_header has the same issue but the call chain is shorter.
