dnsdist: Double-check we only increment the outstanding counter once #8113
At least one user of 1.4.0-beta1 has reported that the outstanding counter is not always properly decremented, or is incremented twice. I have not been able to reproduce it so far but let's make sure we can only increment it once per TCP connection.

3 of 5 checks passed
Update on this: we still see the problem occurring even after this change.
Here is an example from one of our systems that is showing this behavior. Pool2 is not decrementing the outstanding counters correctly. The cause for the failure to decrement is unknown. We do not have reproduce-able trigger circumstances, but do see it happening often and is causes build-up that renders the outstanding policy ineffective.
