gpu: nvgpu: cleanup the seq for railgate seq

Browse Source 
- Perfmon cmds are non-blocking calls and response
  may/may-not come during railgate sequence for the
  perfmon command sent as part of nvgpu_pmu_destroy call.
- if response is missed then payload allocated will not be
  freed and allocation info will be present as part seq data
  structure.
- This will be carried forward for multiple railgate/
  rail-ungate sequence and that will cause the memleak
  when new allocation request is made for same seq-id.
- Cleanup the sequence data struct as part of nvgpu_pmu_destroy
  call by freeing the memory if cb_params is not NULL.
