RDMA/hns: Fix recv CQ and QP cache affinity

RDMA/hns: Fix recv CQ and QP cache affinity

Currently driver enforces affinity between QP cache and send CQ
cache, which helps improve the performance of sending, but doesn't
set affinity with recv CQ cache, resulting in suboptimal performance
of receiving.

Use one CQ bank per context to ensure the affinity among QP, send CQ
and recv CQ. For kernel ULP, CQ bank is fixed to 0.
