iio: hid-sensor-prox: Fix incorrect OFFSET calculation

Browse source 
[ Upstream commit 79dabbd505210e41c88060806c92c052496dd61c ]

The OFFSET calculation in the prox_read_raw() was incorrectly using the
unit exponent, which is intended for SCALE calculations.

Remove the incorrect OFFSET calculation and set it to a fixed value of 0.
