The flag flow_counter_en is eliminated from the code. The Verbs create counter function just returns an error if no counter support presented in the system. If there is no any of Flow counters configuration macro defined the log message is emited, indicating the missing counter support. mlx5_flow_validate_action_count() fuctnion is also updated due to flow_counter_en flag removal.
