pcm plugs: rework the alsa config cleanup
The alsa config (for softvol, routes, rate conversion ...) was cleaned up by the owner stream or zone, at their deletion time. This was a mistake, because when the stream or zone creation was not complete, the cleanup of the configuration was not done. Instead of doing that, the config is attached to the plug objects as private data (in the AlsaPcmCtlT structure). Since the AlsaPcmCtlT are always recorded in the creation transaction, it is easy to call the cleaning callback (when it exists) when the transaction is deleted.
