iio: st_sensors: Fix indio_dev->trig assignment
commit f0e84acd7056e6d7ade551c6439531606ae30a46 upstream.
This can result in wrong reference count for trigger device, call
iio_trigger_get to increment reference.
Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion
with Jonathan.
