tdfxDDWriteDepthPixels can be called with mask == NULL.

Browse source 
Via depth_test_pixels (swrast/s_depth.c), tdfxDDWriteDepthPixels can
be called with mask == NULL.  Test for this condition in the places
where mask might be dereference.  This matches the behavior of several
other functions in this file with a 'const GLubyte mask[]' parameter.
