All the scaling of the KXSD9 involves multiplication with a fraction number < 1. However the scaling value returned from IIO_INFO_SCALE was unpredictable as only the micros of the value was assigned, and not the integer part, resulting in scaling like this: $cat in_accel_scale -1057462640.011978 Fix this by assigning zero to the integer part.
