Chad Versace 263daba7e6 dri: Do not create DRI2 buffers for unrecognized DRI2 buffer tokens 
Before this commit, if a client were to request an unrecognized DRI2
buffer, such as DRI2BufferStencil, then I830DRI2CreateBuffer() allocated
and returned an X-tiled buffer by accident. The problem was that
unrecognized tokens were caught by the default case of a switch statement.

Now, when given unrecognized DRI2 tokens, I830DRI2CreateBuffers() returns
null.

This shouldn't break older Mesa versions, because they never query (via
DRI2GetBuffersWithFormat) for the drawable's DRI2BufferStencil.
