d3dx9: Get rid of constant's length checking for matrix in set_constants().
When count in const_upload_info is calculated precisely (considering actual constant set length), boolean matrix setting fall in direct copy path, unless transpose is required. The case of incomplete last row for matrix should be handled in set_constants() for transposed boolean constant only.
