gpu: nvgpu: use correct gr_config pointer to return tpc masks

Browse Source 
In gk20a_ctrl_get_tpc_masks() receive gr_config pointer from caller
instead of extracting with nvgpu_gr_get_config_ptr().

GR engine current instance value is not set here so this was always
returning 0th instance gr_config pointer.
