In exynos4210 display update function, we were acquiring DisplaySurface
pointer before calling screen resize function, not paying attention that resize
procedure can replace current DisplaySurface with newly allocated one.
Right thing to do is to initialize DisplaySurface AFTER a call to resize
function.
