RDMA/hns: Fix querying wrong SCC context for DIP algorithm

Browse source

When using DIP algorithm, all QPs establishing connections with
the same destination IP share the same SCC, which is indexed by
dip_idx, but dip_idx isn't necessarily equal to qpn. Therefore,
dip_idx should be used to query SCC context instead of qpn.
