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

SCCC (SCC Context) is a context with QP granularity that contains
information about congestion control. Dump SCCC and QPC together
to improve troubleshooting.

When dumping raw QPC with rdmatool, there will be a total of 576 bytes
data output, where the first 512 bytes is QPC and the last 64 bytes is
SCCC. When congestion control is disabled, the 64 byte SCCC will be all 0.

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

RDMA/hns: Dump whole QP/CQ/MR resource in raw

Currently, some fields in the QP/CQ/MR resource can be dumped by
rdma-tool, but this information is not enough. It is very
inconvenient to continue to expand on the current field, and it
will also introduce some trouble to parse these raw data.

This patch dump whole resource in raw to avoid the above problems.

RDMA/hns: Fix memory leak on 'context' on error return path

Currently, the error return path when the call to function
dev->dfx->query_cqc_info fails will leak object 'context'. Fix this by
making the error return path via 'err' return return codes rather than
-EMSGSIZE, set ret appropriately for all error return paths and for the
memory leak now return via 'err' rather than just returning without
freeing context.
