gpu: nvgpu: fix race condition in pmu_rpc_handler
There was a race condition between pmu_rpc_handler and
nvgpu_pmu_rpc_execute. The later could free the buffer before
pmu_rpc_handler could access related data.
Added explicit field in rpc_payload, so that nvgpu_pmu_rpc_execute
can wait until pmu_rpc_handler completes.
