gpu: nvgpu: Remove extra perf load RPC

Browse Source 
1.Remove perf_pmu_load which calls the perf load RPC.
  This is already done in pmu_vfe_load and needs only once.
2.Replace LOAD with VF_INVALIDATE.
  MSG_ID_VFE_CALLBACK should call VF_INVALIDATE and not LOAD.
3.Move the clk arb WQ after VF_INVALIDATE for synchronization.
4.Move the perf load RPC after PMU setup.
