Wait for remote animation to stop freezing display

If display is rotated 180 degree, the display might not have
configuration change. And if there is remote rotation and it hasn't
done, the rotation of display is still the old one. Once there is
a path calls stop-freezing-display, the rotation animation will be
executed directly with 0 degree delta. And if the activity needs to
relaunch, there will be obvious flickering.
