Implement alloc_hw_port_stats and get_hw_stats APIs to support querying
MANA VF port level statistics from rdma stat tool.
Example output from rdma stat tool:
$rdma statistic show link mana_0/1 -p
link mana_0/1
requester_timeout 45
requester_oos_nak 0
requester_rnr_nak 0
responder_rnr_nak 0
responder_oos 0
responder_dup_request 0
requester_implicit_nak 0
requester_readresp_psn_mismatch 0
nak_inv_req 0
nak_access_error 0
nak_opp_error 0
nak_inv_read 0
responder_local_len_error 0
requestor_local_prot_error 0
responder_rem_access_error 0
responder_local_qp_error 0
responder_malformed_wqe 0
general_hw_error 6
requester_rnr_nak_retries_exceeded 0
requester_retries_exceeded 5
total_fatal_error 6
received_cnps 0
num_qps_congested 0
rate_inc_events 0
