    net/mlx5: Introduce and use mlx5_esw_is_manager_vport()

    Currently esw_enable_vport() does vport check for zero to enable drop
    counters regardless of execution on ECPF/PF.
    While esw_disable_vport() considers such scenario.

    To keep consistency across code for checking for manager_vport,
    introduce and use mlx5_esw_is_manager_vport() to check if a specified
    vport is eswitch manager vport or not.
