Previously the orientation was wrong after suspend and resume.
When the camera app is resumed behide the lock screen, it
orinteation is portrait. When users slide to unlock the screen,
surfaceChanged is called and the orientation is landscape.
The camera app stops the preview, sets the display orientation,
and starts the preview. Overlay should be destroyed if the
orientation has changed.
