RDMA/mana_ib: Add port statistics support

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
    num_qps_recovered 0
    current_rate 100000
