Add support to dump SRQ resource in raw format.

This patch relies on the corresponding kernel commit aebf8145e11a
("RDMA/core: Add support to dump SRQ resource in RAW format")

Example:
$ rdma res show srq -r
dev hns3 149000...

$ rdma res show srq -j -r
[{"ifindex":0,"ifname":"hns3","data":[149,0,0,...]}]
