Subject: [PATCH] cf-socket: store errno from do_connect in ctx->error

This fixes a misleading log in verbose mode when ipv6 connectivity isn't
available, presumably also in other cases:

```
* Immediate connect fail for 2a00:1450:4028:806::200e: Network is unreachable
* connect to 2a00:1450:4028:806::200e port 443 from :: port 0 failed: Success
```

Closes #21914
