Bug 232193 – Remove unnecessary refcount increase when using m_player in MediaPlayerPrivateRemote

• Status: NEW
• Component: Media

[Jean-Yves Avenard [:jya]]

As mentioned in: https://bugs.webkit.org/show_bug.cgi?id=232124#c3

We have a lot of this code pattern:
```
    if (RefPtr player = m_player.get())
        m_player->addAudioTrack(addResult.iterator->value);
```

there's no side effect possible when calling m_player here, so there's no need to keep a strong reference :

doing:
```
    if (m_player)
        m_player->addAudioTrack(addResult.iterator->value);
```

is fine
