_math_matrix_is_dirty() should only be used to decide if we need to
run _math_matrix_analyse(). We already decided that we had a new
texture matrix when we called _mesa_update_texture_matrices() so
we need to set _TexMatEnabled correctly otherwise we might
incorrectly return _NEW_FF_VERT_PROGRAM | _NEW_FF_FRAG_PROGRAM in
the following if-statement.
