Takashi Iwai e35f6117e0 ALSA: line6: Sync the pending work cancel at disconnection 
commit 68359a1ad8447c99732ebeab8c169bfed543667a upstream.

Recently syzkaller reported a UAF in LINE6 driver, and it's likely
because we call cancel_delayed_work() at the disconnect callback
instead of cancel_delayed_work_sync().  Let's use the correct one
instead.
