staging: iio: tsl2x7x_core: Fix standard deviation calculation
commit cf6c77323a96fc40309cc8a4921ef206cccdd961 upstream.
Standard deviation is calculated as the square root of the variance
where variance is the mean of sample_sum and length. Correct the
computation of statP->stddev in accordance to the proper calculation.
