Damage re-used shadow scanout buffer using new transforms.

When the shadow scanout buffer can be re-used, the underlying framebuffer
area must be damaged so that the scanout will be repainted. This patch
delays the addition of that damaged area until after the transform in the
crtc has been updated, otherwise the old transform would have been used and
the wrong area repainted.
