Avoid ImageWallpaper IllegalStateException
It's possible that WallpaperService calls surface.release() between
lockCanvas and unlockCanvasAndPost, which gives the exception from
b/337287154 (IllegalStateException: surface has already been released).
To avoid that, we use a second lock that synchronizes the drawing and
the onSurfaceDestroyed method. This makes sure that we are done drawing
(or haven't started drawing) when we exit onSurfaceDestroyed().
