PR #306 broke russh config parsing
for me.

My ssh config looks roughly like this:

```
Host *
    Common settings
Host wanted
   Host-specific settings
```

Before #306 common settings were
ignored, but after - common settings were applied, yet config parser
stops right on next `Host` section start, so settings I need were
ignored instead.

This PR brings behavior closer to what openssh itself does - for
requested host, it applies all the settings with maching glob, not only
the first one.
