ALSA: aloop: Add missing cable lock to ctl API callbacks
commit 76b3421b39bd610546931fc923edcf90c18fa395 upstream.
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.
