Avoid MotionEvent no finish raise unnecessary ANR

In Monkey test. if Trackball MotionEvent and FocusEvent come together.
motionEvent will be put to batches , Didn't call onBatchedInputEventPending due to FocusEvent Return early.
So the motionEvent would't be handled and finish, And the related inputChannel would't receive inputevents due to FocusWindow change.
Finally raise unnecessary ANR.
