hwmon: (coretemp) Further relax temperature range checks

Further relax temperature range checks after reading the IA32_TEMPERATURE_TARGET
register. If the register returns a value other than 0 in bits 16..32, assume
that the returned value is correct.

This change applies to both packet and core temperature limits.
