RDMA/hns: Fix CQ and QP cache affinity

Browse source

[ Upstream commit 9e03dbea2b ]

Currently, the affinity between QP cache and CQ cache is not
considered when assigning QPN, it will affect the message rate of HW.

Allocate QPN from QP cache with better CQ affinity to get better
performance.

Fixes: 71586dd200 ("RDMA/hns: Create QP with selected QPN for bank load balance")
