hwmon: (max6697) Fix underflow when writing limit attributes
Using DIV_ROUND_CLOSEST() on an unbound value can result in underflows.
Indeed, module test scripts report:
temp1_max: Suspected underflow: [min=0, read 255000, written -9223372036854775808]
temp1_crit: Suspected underflow: [min=0, read 255000, written -9223372036854775808]
Fix by introducing an extra set of clamping.
