Mark Zhang 5937552b42 rdma: Add "stat qp show" support 
This patch presents link, id, task name, lqpn, as well as all sub
counters of a QP counter.
A QP counter is a dynamically allocated statistic counter that is
bound with one or more QPs. It has several sub-counters, each is
used for a different purpose.

Examples:
$ rdma stat qp show
link mlx5_2/1 cntn 5 pid 31609 comm client.1 rx_write_requests 0
rx_read_requests 0 rx_atomic_requests 0 out_of_buffer 0 out_of_sequence 0
duplicate_request 0 rnr_nak_retry_err 0 packet_seq_err 0
implied_nak_seq_err 0 local_ack_timeout_err 0 resp_local_length_error 0
resp_cqe_error 0 req_cqe_error 0 req_remote_invalid_request 0
req_remote_access_errors 0 resp_remote_access_errors 0
resp_cqe_flush_error 0 req_cqe_flush_error 0
