dnsdist: Insert the response into the ringbuffer right after sending it

The current code could have tried to read a new query before coming
back to the insertion, resetting the state in the process and leading
to recording a wrong backend or worse, to a NULL-pointer dereference
if the new query was dropped or self-answered (no backend then).
