net/mlx5: E-switch, derive manager vport from device capability

Browse source

mlx5_eswitch_manager_vport() hardcoded the e-switch manager vport as
either the ECPF or the host PF. Read esw_manager_vport_number from the
e-switch capability when esw_manager_vport_number_valid is set, so the
manager vport can be a VF - a prerequisite for VFs acting as e-switch
managers. Keep the previous mapping as fallback when the capability does
not report a number.
