iio: dac: ds4422/ds4424 fix chip verification

commit 60f22086 upstream.

The ds4424_get_value function takes channel number as it's 3rd
argument and translates it internally into I2C address using
DS4424_DAC_ADDR macro. The caller ds4424_verify_chip was passing an
already translated I2C address as its last argument.
