dnsdist: Fix a crash when TCP queries and responses keep coming

It happens when we keep finding queries waiting for us on the incoming
TCP socket from the client, and responses waiting for us on the TCP
socket to the backend after forwarding a new query. This is quite
unlikely but not impossible to happen, as reported by Renaud Allard
(many thanks for taking the time to investigate the issue!).
