gpu: nvgpu: cancel clean up before update_fn_work

In gk20a_channel_suspend(), we first cancel worker
thread update_fn_work and then cancel job clean up worker

But it is possible that we re-schedule update_fn_work from
job cleanup worker after it was cancelled
And in that case worker update_fn_work might run after
we poweroff GPU

Fix this by first cancelling job clean up worker and
then update_fn_work worker
