Fix bug slowing down pgbench when -P is used.

Browse Source 
A removed check in ba3deeefb made all threads but the main one busy-loop
when -P was used. All threads computed the time to the next time the
progress report should be printed, but only the main thread did so and
re-scheduled it only for the future.
