EAGAIN when trying to read from a newly created TCP connection using `Deno.connect`

## Reproduction

```ts
import { Deno } from "@deno/node-shims";

const r = await Deno.connect({ port: 80, hostname: "google.com" });
await r.read(new Uint8Array(100));
```

## Current Behavior

Throws EAGAIN.

## Expected Behavior

Should block until data is available, but not necessarily the amount of the data requested to be read.
