ALSA: aloop: Fix initialization of controls

commit 168632a495f49f33a18c2d502fc249d7610375e9 upstream.

Add a control to the card before copying the id so that the numid field
is initialized in the copy. Otherwise the numid field of active_id,
format_id, rate_id and channels_id will be the same (0) and
snd_ctl_notify() will not queue the events properly.
