Vincent Lu 8c53b54649 gpu: nvgpu: use signed int in binary search ...

In case of the target we want to find is less than all candidates,
end = mid - 1U will finally execute with mid = 0, which makes end =
0xFF..FF.
We'll have an invalid memory access in this case.
Change u32 to int for start, mid and end variables in
allowlist_offset_search.
This case also applied for allowlist_range_search.
