sna/dri2: Prevent the sw cursor from copyig to a buffer as we discard it
During swapbuffers, the sw cursor tries to write to the old buffer.
Ordinary this is not an issue as we are discarding it, but under
TearFree that write causes us to instantiate the shadow buffer with a
possible recursion into set_bo and mayhem.

and maybe the other odd issue. However, I still want to dig into why you are
hitting the sw cursor fallback.</pre>
