MALI: mali_ukk_core: Fix potential kernel stack info leak

The kargs structs in wait_for_notification_wrapper()
and get_user_settings_wrapper() have unions in them,
and since nothing initializes the full structure,
there can be holes where we pass uncleared stack
data out to userspace.

Thus this patch memsets the entire structure to zero
before filling and passing them to userspace.

ANDROID: video: adf: Avoid directly referencing user pointers

Enabling KASAN on a kernel using ADF causes a number of places where
user-supplied pointers to ioctls  pointers are directly dereferenced
without copy_from_user or access_ok.
