Nouveau - Feb 2011 - [PATCH] Also flush from the BlockHandler.

- The fact that commit 02c50db307a4e4eeb87f7db5d401bc53cce3b21f
  fixed missing text for some people proves this is needed.
  That commit should have only improved latency a bit.
- The FlushCallback is still needed for DRI2 texture_from_pixmap.
- See bugs.fd.o #33977 for discussion.
