iio: humidity: hts221: remove usage of iio_priv_to_dev()
We may want to get rid of the iio_priv_to_dev() helper. That's a bit uncertain at this point. The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. For this driver, removing the iio_priv_to_dev() helper means passing the iio_dev object on hts221_allocate_buffers() & hts221_allocate_trigger().
