hwmon: (sht4x) do not overflow clamping operation on 32-bit platforms
On 32-bit platforms, long is 32 bits, so (long)UINT_MAX is less than (long)SHT4X_MIN_POLL_INTERVAL, which means the clamping operation is bogus. Fix this by clamping at INT_MAX, so that the upperbound is the same on all platforms. Signed-off-by: Jason A.
