Subject: [PATCH] return statement to exit reading loop

Merges PR#2414

I used this example to start building my WebSocket application, however, I noticed that upon removing the echoing in the on_read method, the server repeatedly throws errors without exiting the method.

You can recreate this problem by replacing the async_write with do_write and cause any error (i.e. client reloads the page).

Adding a return statement here would make debugging for future changes much easier and it wouldn't harm the existing echoing in any way.
