iio: adc: ad_sigma_delta: Fix indio_dev->trig assignment
commit 9e5846be33277802c0c76e5c12825d0e4d27f639 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.
