iio: temperature: hid-sensor-temperature: switch to non-devm iio_device_register()

Avoid using devm_iio_device_register(), as this driver requires explicit
error handling and teardown ordering.

With devm_iio_device_register(), IIO device remains registered until the
devres cleanup phase. However, driver's remove() callback removes the
sensor hub callback and trigger support. This can create a race window
where IIO device is still visible and read_raw() requests are issued.
These requests might call sensor_hub_input_attr_get_raw_value(), which
waits up to 5 seconds for a response from the sensor hub callback that
has already been removed.

Add an explicit iio_device_unregister() call in the teardown path to
ensure deterministic cleanup, so that userspace can no longer access the
device once backend resources begin to be dismantled.
