RDMA/hns: Support CQ's restrack raw ops for hns driver

The CQ raw restrack attributes come from the queue context maintained by
the ROCEE.

For example:

$ rdma res show cq dev hns_0 cqn 14 -dd -jp -r
[ {
        "ifindex": 4,
        "ifname": "hns_0",
        "data": [ 1,0,0,0,7,0,0,0,0,0,0,0,0,82,6,0,0,82,6,0,0,82,6,0,
		  1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,
		  6,0,0,0,0,0,0,0 ]
    } ]
