ObjectDownloadListener: Return from onWritePossible when data is written

When buffer was written not only call AsyncContext#complete() but also
return from the ObjectDownloadListener#onWritePossible(). This avoids
endless loop after upgrading from Jetty 9.3.x to 9.4.x lines.

In Jetty example implementation:[1] the return statemnt is also used:

  // If we are at EOF then complete
  if (len < 0)
  {
    async.complete();
    return;
  }
