Guenter Roeck 6b101116ae hwmon: (lm90) Add range check to set_update_interval ...

When writing the update_interval attribute, the parameter value was
not range checked, which could cause an integer overflow and result
in an arbitrary update interval. Fix by limiting the value range to
<0, 100000>.
