Subject: [PATCH 3/4] iio: hid-sensor-trigger: Use iio->trig instead trig field internal structure

Use iio->trig instead of attrb->trig as parameter of iio_trigger_unregister
and iio_trigger_free. This allows one HID sensor driver to create
multiple iio devices. In this case common attributes are shared and
there can be one instance for the structure containing common attributes
for all iio devices.
