RDMA/hns: Append SCC context to the raw dump of QP Resource

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8B8HH



--------------------------------------------------------------------------

QP and SCC are bound one by one. Therefore, QPC and SCCC can
be combined for output. When the SCC output is disabled, the
QPC output is normal, and the SCCC output is all 0.

The 512-byte QP context is appended with 64-byte SCC context.

Example:
$rdma res show qp -jpr
[ {
        "ifindex": 0,
        "ifname": "hns_0",
	"data": [ 67,0,0,0... 512bytes
		  4,0,2... 64bytes]
    },...
    } ]
