[MINOR] proxy: make session rate-limit more accurate

Patch d9bbe17b used to limit the rate-limit to off-by-one to avoid
a busy loop when the limit is reached. Now that the listeners are
automatically disabled and queued when a limit is reached, we don't
need this workaround anymore and can bring back the most accurate
computation.
