video: Don't resize moved fullscreen windows if the display mode switch failed

Browse source 
If an exclusive fullscreen window is moved between displays, SDL_UpdateFullscrrenMode can kick the window out of fullscreen if the display onto which it was moved doesn't have a matching video mode. Check the return code and clear the fullscreen flag and skip the resize if the window is no longer fullscreen.
