iio: adc: ad7280a: fix ad7280_store_balance_timer()

Use correct argument to iio_str_to_fixpoint() to parse 3 decimal places.

iio_str_to_fixpoint() has a bit of an unintuitive API where the
fract_mult parameter is the multiplier of the first decimal place as if
it was already an integer.  So to get 3 decimal places, fract_mult must
be 100 rather than 1000.
