hwmon: (ntc_thermistor) Avoid math overflow
commit d3d89c468ceebbcf9423d1a3d66c5bf91f569570 upstream.
The ntc thermistor code was doing math whose temporary result might
have overflowed 32-bits. We need some casts in there to make it safe.
In one example I found:
- pullup_uV: 1800000
- result of iio_read_channel_raw: 3226
- 1800000 * 3226 => 0x15a1cbc80
