iio: imu: adis16480: make sure provided frequency is positive
commit 24e1eb5c0d78cfb9750b690bbe997d4d59170258 upstream.
It could happen that either `val` or `val2` [provided from userspace] is
negative. In that case the computed frequency could get a weird value.
Fix this by checking that neither of the 2 variables is negative, and check
that the computed result is not-zero.
Fixes: e4f959390178 ("iio: imu: adis16480 switch sampling frequency attr to core support")
