add missing NULL, use driCreateConfigs()
tdfx_dri driver in Mesa 7.1.0 is missing some parts of update, at least:
1) tdfxExtensions is missing terminating NULL, which leads to X server
crash on startup if DRI is enabled
2) configs creation was not updated to use driCreateConfigs(), which
leads to no available visuals
Patch already merged in Mesa 7.2 release.
