net/mlx5: LAG, Support LAG over Multi-Host NICs

New multi-host NICs provide each host with partial ports,
allowing each host to maintain its unique LAG configuration.

On these multi-host NICs, the 'native_port_num' capability
is no longer continuous on each host and can exceed the
'num_lag_ports' capability. Therefore, it is necessary to
skip the PFs with ldev->pf[i].dev == NULL when querying/modifying
the lag devices' information.
There is no need to check dev.native_port_num against ldev->ports.
