heater: Do not flush look-ahead queue on a heater temperature update

The print_time parameter of heater.set_temp() is not currently used
and it isn't necessary to flush the look-ahead queue just get the
print_time.  Remove the parameter from heater.set_temp() to avoid
flushing the look-ahead queue.
