Revert "sound: include ALSA sound card id in /dev/snd/by-id/ links"

Browse source 
This reverts commit 68bffc607f.

After discussing this with Kay we decided to drop this again as by-id
links only make sense for devices that have a unique serial id. If they
don't any attempts to make them unique have the side effect of
nourishing assumptions by users that cannot be met, as the by-id device
link of a device could differ depending on the history of simultaneously
plugged in device.

So, to make sure that all device nodes follow the same rules for by-id/
symlinks, drop this patch again.
