evas-wayland-shm: Fix rotation for wayland shm engine

Prior to this fix, window rotation was not operating correctly and the
surface contents would get rendered at the wrong size and position.
This patch fixes the engine so that rotation operates properly now.

NB: Tested with the Window States(2) test in elementary

Thanks to shiin for reporting :)
