iio: magnetometer: yas530: Change range of data in volatile register

In function yas5xx_volatile_reg(), register "YAS5XX_MEASURE_DATA + 8" shouldn't
be volatile as we count from 0 to 7 here.

Instead of lowering the number from 8 to 7, the operator "<=" is replaced by
"<". The size of the measure data array is 8, therefore it's more natural to
use 8 as a constant.

This change is of low importance as the "+ 8" register isn't called.
