si-adapter: handle dont-remix streams
Don't-remix streams don't change their channel mapping based on the device they connect to but are always configured with their default channel mapping, just like devices. This fixes the gnome-control-center channel test. This patch also removes the 1 channel -> many patch because it is not the right thing to do in this case and should be implemented with some proper channel mapping patch later.
