hwmon: (gpio-fan) Prevent overflow problem when writing large limits
commit 2565fb05d1e9fc0831f7b1c083bcfcb1cba1f020 upstream.
On platforms with sizeof(int) < sizeof(unsigned long), writing a rpm value
larger than MAXINT will result in unpredictable limit values written to the
chip. Avoid auto-conversion from unsigned long to int to fix the problem.
