[BUG] NDS-H data generator stalls after scale factor 150

[JayjeetAtGithub]

Describe the bug
Currently, libcudf supports upto 32-bit integers. Hence, the NDS-H data generator which is built using libcudf can only generate upto 2,147,483,647 rows before it hits the row limit. For NDS-H, this translates to a scale factor of ~350 (The lineitem table, which is the largest NDS-H table, has ~6M rows, so the largest lineitem table that can be generated is of scale factor 350). But, when we tried running the NDS-H data generator with scale factor > 150, it stalled indefinitely. The highest scale factor that it was able to successfully generate was 150. This was observed both with un-managed and managed memory, and the execution stalled even though there was enough memory left.

Steps/Code to reproduce bug
Run the data generator with scale factor > 150

Expected behavior
The NDS-H data generator should be able to generate upto scale factor ~350.
