setopt: fix checking range for CURLOPT_MAXCONNECTS

Browse source 
- Use upper limit INT_MAX instead of UINT_MAX.

UINT_MAX doesn't work as the max value for the variable since it is
passed as a long and becomes -1 on platforms that have same sized
int and long, like Windows.

Closes https://github.com/curl/curl/pull/20414
