CarKeytuardView is inflated when CarKeyguardView is first started, and mBouncer is assigned a value onFinishInflated. Since some of the view-related requests that reference mBouncer could be called before that event, we need to add null checks for them. Such a check is redundant for methods that check for mShowing, since if mShowing is true, it is guaranteed that mBouncer is assigned a value.
