iio: hid-sensor-attributes: Check sample_frequency/hysteresis write data legitimacy

Neither sample frequency value nor hysteresis value can be set to be a
negative number, check and return "Invalid argument" if they are negative.

If not do this change, sample_frequency will be set into some unknown
value, read hysteresis value after write negative number will return
"Invalid argument".
