Sunny Li 516023e1e4 gpu: nvgpu: sysfs adding NULL pointer check ...

golden image size will be set when memory allocated.
See function:
- nvgpu_gr_obj_ctx_init

If golden image size is 0, gr_golden_image should be a NULL
pointer in most cases. So add NULL pointer checking in
tpc_pg_mask_store to avoid NULL pointer exception.
