SwapBuffersRegionNOK: invert rectangles on y axis
The EGL_NOK_swap_region2 spec states that the rectangles are specified with a bottom-left origin within a surface coordinate space also with a bottom left origin, so this patch ensures the rectangles are flipped before passing them on to dri2_copy_region.
