ALSA: control_led: Use guard() for locking

Browse source

We can simplify the code gracefully with new guard() macro and co for
automatic cleanup of locks.

A couple of functions that use snd_card_ref() and *_unref() are also
cleaned up with a defined class, too.

Only the code refactoring, and no functional changes.
