The other cacheable objects require pointers to stay in the ARC
pointing to blocks in the L2ARC. If the DDT required this,
L2ARC-ification would be pointless since DDT entries aren't much
smaller than ARC->L2ARC pointers, so from what I hear it is actually
special in some way though I don't know precisely what way.
