ALSA: aloop: Add missing cable lock to ctl API callbacks Some control API callbacks in aloop driver are too lazy to take the loopback->cable_lock and it results in possible races of cable access while it's being freed. It eventually lead to a UAF, as reported by fuzzer recently. This patch covers such control API callbacks and add the proper mutex locks.
