ALSA: timer: Fix leak in events via snd_timer_user_ccallback

commit 9a47e9cff994f37f7f0dbd9ae23740d0f64f9fe6 upstream.

The stack object “r1” has a total size of 32 bytes. Its field
“event” and “val” both contain 4 bytes padding. These 8 bytes
padding bytes are sent to user without being initialized.
