Subject: [PATCH] fix return value of snd_pcm_rewind()/snd_pcm_forward() to return how much actually has been rewound, instead of what actually could have rewound

Make snd_pcm_plugin_rewind()/_forward() actually return how much has

been rewound/forwarded instead of how much could have been

rewounded/forwarded. This makes the code actually do what the

documentation of snd_pcm_rewind() suggests.
