A user reports a really bad temperature on Ryzen 1950X.
k10temp-pci-00cb
Adapter: PCI adapter
temp1: +4294948.3°C (high = +70.0°C)
This will happen if the temperature reported by the chip is lower than
the offset temperature. If that happens, let's report a temperature
of 0 degrees C.
Fixes: 1b50b776355f ("hwmon: (k10temp) Add support for temperature offsets")
