net/mlx5: E-switch, disable host functions for a non PF e-switch manager

Browse Source 
mlx5_esw_host_functions_enabled() only treated host functions as
disabled for an ECPF manager.

To support a non PF acting as an e-switch manager, add a check for a non
PF e-switch manager that treats host functions as disabled. This will
avoid allocating a host-PF vport in mlx5_esw_vports_init().

With host functions disabled for non PF, its e-switch is the expected
manager + uplink only.
