Write queue after connect windows

Wait wait, we need it if we connect with IOCP.

Look at this:
```
+  if (handle->type == UV_NAMED_PIPE &&
+      !handle->connect_req &&
+      !(handle->flags & UV_HANDLE_WRITABLE))
+    return UV_ENOTCONN;
```

We set connect_req when we are connecting with IOCP, if we connect immediately, then the writable flag is set immediatel so we don't need to connect_req for this guard to kick in. That is what I am saying, we don't really need to touch connect_req if we succeed without iocp.
