I wonder if it's worth it... the alternative would be for cxgb3 etc. to
just return STag 0 from get_dma_mr if only local access rights are
requested. But of course as we discussed later STag 0 doesn't do PD
protection, if anyone cared.
We can always change it later anyway.

I could still change cxgb3 to do this if you want. We can have both...
