iotests: Make 136 less flaky
136 executes some AIO requests without a final aio_flush; then it
advances the virtual clock and thus expects the last access time of the
device to be less than the current time when queried (i.e. idle_time_ns
to be greater than 0). However, without the aio_flush, some requests
may be settled after the clock_step invocation. In that case,
idle_time_ns would be 0 and the test fails.
Fix this by adding an aio_flush if any AIO request other than some other
aio_flush has been executed.
