[Mesa-dev] [PATCH] nvc0: do not force re-binding of compute constbufs on Fermi

[Samuel Pitoiset]

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 binded for compute.
