Nitin Kumbhar 51dc43de1e gpu: nvgpu: change return type of __hweight ...

Instead of using unsigned long for all __hweight variants
use unsigned int as it's sufficient to hold the result
without any data loss.

This also matches with return type used in other OS variants
like Linux and helps avoid CERT-C errors.

Error: CERT INT31-C:
drivers/gpu/nvgpu/common/gr/fs_state.c:76:
cert_violation: Casting "__hweight32(val)" from "unsigned long" to
 "unsigned int" without checking its value may result in lost or
 misinterpreted data.
