Fix GH-19798: XP_SOCKET XP_SSL: Incorrect condition for Win

This fixes incorrect type conversion and subsequent check for Windows
where returned socket is not an int.

It should be noted that this is not really an issue as previous int
would get negative so the check should still work. The issue actually
happens only in master (PHP 8.5) where refactoring has been done and the
type changed.

Closes GH-19881
