udev: Fix sound.target dependency
The recent bug report indicated a race at device creation and the
sound.target dependencies, and the cause turned out to be the condition
of the sound.target trigger. Currently it's set for "card*", but this
is actually the parent object; i.e. the sound.target is triggered before
the sound devices are created.
For assuring the whole sound device creations beforehand, we need to use
"controlC*" instead of "card*"; as already described in
78-sound-card.rules, this is guaranteed to be the last device, and can
be used as a synchronization point.
