[Stability]: fix system_server crash issue caused by fd leak.

If an app incorrect use of registerListener, it will cause
system_server socket fd leak, for example:
    protected void onResume() {
        super.onResume();
        mSensorManager.registerListener(new MySensorEventListener(),
                mSensor, SensorManager.SENSOR_DELAY_UI);
Each time a new SensorEventQueue, then in the system_server
will open a new socket fd, as time increases system_server's
fd will be more than 1024 and crash, so we needed add count limit
for sensor listener to improve the system stability.

Test: use the apk attached in the issue
