Debarshi Dutta 11d27743f8 gpu: nvgpu: add NULL checks before freeing ZBC and ZCULL ...

Disabling NVGPU_SUPPORT_MIG in suspend path leads to inconsistencies.
During driver removal without the flag set, the driver still tries
to free structures that might not have been allocated in the first place.
e.g. nvgpu_gr_zbc_deinit, nvgpu_gr_zcull_deinit.

Added NULL checks for ZBC and ZCULL structures before freeing them as a
solution.
