Fix for a native socket engine on Windows

nativeConnect calls WSAConnect, tests its return value and  then in case of SOCKET_ERROR
checks WSAGetLastError and calls getsockopt to extract SO_ERROR. While MSDN
says that getsockopt  should clear the error, it's not true and this error can later affect in some
weird way the next WSAConnect attempt/or nativeConnect's logic.
Found in tst_qtcpsocket::bindThenResolveHost failing in this scenario: QHostInfo
has a list of invalid/valid addresses,
and as a result test doing strange things in waitForConnected and failing (and sometimes
passing).
