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.
