pgbench: Fix overflow in table populating when rows >= 2^31-1

Browse Source 
Using a scale factor large enough so as the number of rows to insert
gets larger than INT32_MAX would cause an infinite loop in
initPopulateTable(), preventing pgbench to finish its initialization.

Oversight in e35cc3b3f2 that has refactored the data generation logic.
