Add macros to get current GR instance id and the pointer nvgpu_gr_get_cur_instance_ptr() nvgpu_gr_get_cur_instance_id() This approach makes sure that the caller is getting GR instance pointer under mutex g->mig.gr_syspipe_lock in MIG mode. Trying to access current GR instance outside of this lock in MIG mode dumps a warning. Return 0th instance in case MIG mode is disabled. Use these macros in nvgpu instead of direct reference to g->mig.cur_gr_instance. Store instance id in struct nvgpu_gr. This is to retrieve GR instance id in functions where struct nvgpu_gr pointer is already available.
