rec: Don't follow referral from the parent to the child for DS queries

It happens if the server does not know about the DS special case.
Treat the delegation as a unsigned NODATA answer in that case.

dnsdist: Fix a data race reported by TSAN in SNMP metrics

Unless I'm mistaken, the report (below) is a false positive since
`std::atomic<T>::operator T` is equivalent to `load()` and
`std::atomic<T>::operator=` to `store()`, but perhaps I'm missing
something.
Note that I could not reproduce the issue using clang++ 11.1.0's
TSAN, only with the one from g++ 11.1.0.
