RDMA/nldev: Add QP numbers to SRQ information

Add QP numbers that are associated with the SRQ to the SRQ information.
The QPs are displayed in a range form.

Sample output:

$ rdma res show srq
dev ibp8s0f0 srqn 0 type BASIC pdn 3 comm [ib_ipoib]
dev ibp8s0f0 srqn 4 type BASIC lqpn 125-128,130-140 pdn 9 pid 3581 comm ibv_srq_pingpon
dev ibp8s0f0 srqn 5 type BASIC lqpn 141-156 pdn 10 pid 3584 comm ibv_srq_pingpon
dev ibp8s0f0 srqn 6 type BASIC lqpn 157-172 pdn 11 pid 3590 comm ibv_srq_pingpon
dev ibp8s0f1 srqn 0 type BASIC pdn 3 comm [ib_ipoib]
dev ibp8s0f1 srqn 1 type BASIC lqpn 329-344 pdn 4 pid 3586 comm ibv_srq_pingpon

$ rdma res show srq lqpn 126-141
dev ibp8s0f0 srqn 4 type BASIC lqpn 126-128,130-140 pdn 9 pid 3581 comm ibv_srq_pingpon
dev ibp8s0f0 srqn 5 type BASIC lqpn 141 pdn 10 pid 3584 comm ibv_srq_pingpon

$ rdma res show srq lqpn 127
dev ibp8s0f0 srqn 4 type BASIC lqpn 127 pdn 9 pid 3581 comm ibv_srq_pingpon
