Playback can get stuck buffering in tunneling mode

[REQUIRED] Issue description

I have to change the following default values inside `DefaultLoadControl` for some reasons.

```bash

When I play a video in tunneling mode, the playback stays stalled on `STATE_BUFFERING`, but the playback without tunneling mode works well.
I guess a difference is that `hasOutputBuffer()` always returns false in tunneling mode.

Is there a way I can avoid the problem?

Thanks in advance for any help!

[REQUIRED] Reproduction steps

1. ExoPlayer demo app version release-v2(2.11.8), enable "Request multimedia tunneling"
2. Play video under SmoothStreaming -> Super Speed
3. While the video is playing in 3 seconds go to pause the video.
4. Wait 5 minutes.
5. Play the video again.
6. While the video is playing a while, observe that the video is frozen.
