ALSA: timer: Fix master timer notification
commit 9c1fe96bded935369f8340c2ac2e9e189f697d5d upstream.
snd_timer_notify1() calls the notification to each slave for a master
event, but it passes a wrong event number. It should be +10 offset,
corresponding to SNDRV_TIMER_EVENT_MXXX, but it's incorrectly with
+100 offset. Casually this was spotted by UBSAN check via syzkaller.
