gpu: nvgpu: Use a callback to free struct gk20a

struct gk20a is now part of nvgpu_os_linux in Linux builds. gk20a.c
still frees struct gk20a by kfree(struct gk20a *), which is wrong.
Create a new function pointer in struct gk20a for freeing the
structure and call kfree(struct nvgpu_os_linux *) instead.
