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

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

For example:

$ rdma res show qp link hns_0 -jp -dd -r
[ {
        "ifindex": 4,
        "ifname": "hns_0",
        "data": [ 2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,4,0,0,0,
		  5,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,255,156,0,0,63,156,0,0,
		  7,0,0,0,1,0,0,0,9,0,0,0,0,0,0,0,2,0,0,0,2,0,0,0,0,0,0,
		  0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
		  0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,63,156,0,
		  0,0,0,0,0 ]
    } ]
