iio: hid-sensor-press: Fix return values
IIO_CHAN_INFO_SAMP_FREQ and IIO_CHAN_INFO_HYSTERESIS cases ignored the actual return values (which could be -EINVAL) and instead returned IIO_VAL_INT_PLUS_MICRO always. Return the actual value obtained from the functions. Both functions return IIO_VAL_INT_PLUS_MICRO upon success. Agreed with by Srinivas.
