Fix pgbench's calculation of average latency, when -T is not used.

Browse Source 
If the test duration was given in # of transactions (-t or no option),
rather as a duration (-T), the latency average was always printed as 0.
It has been broken ever since the display of latency average was added,
in 9.4.
