Fix the problem that AccessibilityNodeInfo maybe null and cause a crash.

If the mAccessibilityDelegate of a view is not null, the mAccessibilityDelegate also has a corresponding AccessibilityNodeProvider object. If the AccessibilityNodeProvider does not overload the createAccessibilityNodeInfo(int virtualViewId) method, the app will crash. This bugfix is to add a non-null judgment here.
