iio: chemical: Use iio_push_to_buffers_with_ts() to provide length for runtime checks.

Browse Source 
This new function allows us to perform debug checks in the helper to ensure
that the overrun does not occur.  Use it in all the simple cases where
either a static buffer or a structure is used in the drivers.
