ALSA: gus: Fix kctl->id initialization

GUS driver replaces the kctl->id.index after assigning the kctl via
snd_ctl_add().  This doesn't work any longer with the new Xarray
lookup change.  It has to be set before snd_ctl_add() call instead.

Fixes: c27e1ef ("ALSA: control: Use xarray for faster lookups")
