gpu: nvgpu: changing page_idx from int to u64

page_idx is an element of the struct nvgpu_semaphore_pool, defined in
include/nvgpu/semaphore.h file.

page_idx can not be negative so changing it from int to u64 and its
related changes in various files.

This also fixes MISRA 10.4 violations in these files.

Jira NVGPU-992
