gpu: nvgpu: fix MISRA 11.2 nvgpu_sgl

Browse Source 
MISRA rule 11.2 doesn't allow conversions of a pointer from or to an
incomplete type. These type of conversions may result in a pointer
aligned incorrectly and may further result in undefined behavior.

This patch addresses rule 11.2 violations related to pointers to and
from struct nvgpu_sgl. This patch replaces struct nvgpu_sgl pointers by
void pointers.
