iio: inv_mpu6050: Fix indio_dev->trig assignment
commit b07e3b3850b2e1f09c19f54d3ed7210d9f529e2c 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.
