Set initial KSV state after inflation

In O and before, KeyguardSecurityVew#reset was always called
before showing the view. In P it's not possible since reset()
will make a series of binder calls and generate jank during
swipe gesture.

Because of this, reset() is called after inflation and only
after the view isn't visible anymore.
