dri2: Invalidate DRI2Buffers upon SetWindowPixmap updates

When transitioning to a redirected or unredirected Window, the Composite
layer modifies the Window's Pixmap. However, the DRI2Buffer for the
Drawable is still pointing to the backing bo of the old Pixmap with the
result that rendering goes astray.

This now also effects DRI2 Drawables that are touched by PresentPixmap.

v2: Fixup the function name after rebasing
