hwmon: (ina2xx) don't accept shunt values greater than the calibration factor

Shunt resistance values greater than the chip's calibration factor make no
sense since the actual value written to the register equals:

<calibration factor> / <shunt>

Bail-out from ina2xx_probe() if the configured value is greater than the
calibration factor.
