nvc0: do not force re-binding of compute constbufs on Fermi 

Re-binding compute constant buffers after launching a grid have no effects
because they are not currently validated and because dirty_cp is not updated
accordingly. This might also prevent weird future behaviours when UBOs will
be bound for compute.
