sst: report correct jack event

The status of jack event is compared bitwise:

[in sound/core/jack.c:snd_jack_report()]
	for (i = 0; i < ARRAY_SIZE(jack_switch_types); i++) {
		int testbit = 1 << i;
		if (jack->type & testbit)
			input_report_switch(jack->input_dev,
					    jack_switch_types[i],
					    status & testbit);
	}

So in order to report the correct events, 3 should be passed instead of 1.
