Divya 04cd344b35 gpu: nvgpu: free rpc_payload when driver is dying ...

- During nvgpu module unload, the poweroff sequence
  will not wait for the ACK from the PMU for the RPCs sent.
- Due to this, rpc_payload struct info will be present
  in pmu seq struct.
- This can lead to memory corruption during unload path.
- To avoid this, return a different value for driver shutting
  down scenario from fw ack function and based on this return value
  free the RPC payload and release the respective pmu sequence struct.
