iio: accel: kxcjk-1013: Increment ref counter for indio_dev->trig
Assigning indio_dev->trig is not a good idea, as this can result in
wrong reference count for trigger device. If assigned, it is better to
increment reference counter by calling iio_trigger_get.
Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion
with Jonathan.
