RDMA/cxgb3: Adjust ORD/IRD (if needed) for peer2peer connections

Browse Source 
NFS/RDMA currently fails to set up connections if peer2peer is on.
This is due to the fact that the NFS/RDMA client sets its ORD to 0.

If peer2peer is set, make sure the active side ORD is >= 1 and the
passive side IRD is >=1.
