iio: hid-sensor-gyro-3d: 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.
