u_vbuf: Mark vbufs incompatible if more were requested than HW supports 

More vertex buffers are used than the hardware supports.  In
principle, we only need to make sure that less vertex buffers are
used, and mark some of the latter vertex buffers as incompatible.
For now, mark all vertex buffers as incompatible.
