[PATCH] staging: iio: cdc: ad7746: set ret on IIO_VOLTAGE case

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

For a IIO_VOLTAGE case, ret is not being set causing an
uninitialized value being returned by ad7746_read_raw. Fix
this by setting ret to IIO_VAL_INT for this specific case.
