commit ca85123354e1a65a22170286387b4791997fe864 upstream.
iio_convert_raw_to_processed_unlocked() assumes the offset is an
integer. Make a best effort to get a valid offset value for fractional
cases without breaking implicit truncations.
Fixes: 48e44ce0f8 ("iio:inkern: Add function to read the processed value")
