[PATCH spice-gtk 1/5] audio: emit stop when the channels are reset

[Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>]

Ensure a hint is given to the client that the channel is reset.

Unfortunately, since the handle may be asynchronous due to coroutine,
the channel functions should be tolerant to a playback/record calls
functions when the channel is stopped.
