UPSTREAM: ALSA: timer: Fix leak in SNDRV_TIMER_IOCTL_PARAMS
(cherry pick from commit cec8f96e49d9be372fdb0c3836dcf31ec71e457e)
The stack object “tread” 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.
