RDMA/hns: Add or remove CQ's restrack attributes

Browse Source 
Remove the resttrack attributes from the queue context held by ROCEE, and
add the resttrack attributes from the queue information maintained by the
driver.

For example:

$ rdma res show cq dev hns_0 cqn 14 -dd -jp
[ {
        "ifindex": 4,
        "ifname": "hns_0",
        "cqn": 14,
        "cqe": 127,
        "users": 1,
        "adaptive-moderation": false,
        "ctxn": 8,
        "pid": 1524,
        "comm": "ib_send_bw"
    },
    "drv_cq_depth": 128,
    "drv_cons_index": 0,
    "drv_cqe_size": 32,
    "drv_arm_sn": 1
}
