Takashi Iwai 404680c7e9 ALSA: timer: Unconditionally unlink slave instances, too
commit ffdd98277f0a1d15a67a74ae09bee713df4c0dbc upstream.

Like the previous fix (commit c0317c0e8709 "ALSA: timer: Fix
use-after-free problem"), we have to unlink slave timer instances
immediately at snd_timer_stop(), too.  Otherwise it may leave a stale
entry in the list if the slave instance is freed before actually
running.
