🐛 Bug Report — Noisy logging on client resets to DiskDirectory services

With this script to trigger an immediate client connection reset pointed at a running workerd DiskDirectory service: (Technically in my setup we have a workerd service fronting that DiskDirectory to do content negotiation, but I don't _think_ that matters here?)
```
const net = require('net');
const socket = new net.Socket();
socket.connect(8080, "127.0.0.1", () => {
socket.write(
'GET / HTTP/1.1\n' +
'Host: localhost\n\n'
);
setTimeout(() => socket.resetAndDestroy(), 0);
});
```

We end up with the following logs on each run:
```

This is particularly noisy/noticeable for me in the case when doing local development using the DiskDirectory service to serve locally-build JS/CSS assets—for which browsers will race the cache and drop unnecessary pending requests on cache hit.
