server: Always update cached socket name after connect.

Fixes a regression introduced by 5c009c17. For IPV6 socket already bound with bind() with IPV6_V6ONLY set to 0 the address returned by getsockname() may change after it is connected to a IPV4 peer (e. g., from :: to ::ffff:192.0.2.128). The effect of blamed commit is that before that Unix getsockname() was called for each ws2_32 getsockname() and after the commit the socket name is cached at bind and connect.
