only allow VERT_ATTRIB_MAX instead of _TNL_ATTRIB_MAX for inputs of vertex programs (fixes a segfault since the result of the shift is undefined otherwise, and it may happen that _TNL_ATTRIB_POINTSIZE will be tried to read, unlike all other attribs this however may be unitialized (might be a bug in itself)).
