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.
Fixes piglit's egl-nok-swap-region test.
