Separate the values "more work to do?" and "amount of work done" in tracepoll. previously, the code used "amount of work done > 0" when it needed "more work to do?" but that's not right, because on the last two calls to traceadvance, no "work" is done (because reclaim work is not measured), but there may still be more work to do.
