devlink: Expose external flag for PCI SF ports

Browse Source 
The external flag is part of the PCI SF port attributes, but unlike the
PCI PF and PCI VF flavours it was never filled into the port dump, so
userspace could not query it directly.

Reporting of the external flag was missed for SF ports. Hence, put
DEVLINK_ATTR_PORT_EXTERNAL for the PCI SF flavour as well, matching what
PCI PF and PCI VF ports already report.

$ devlink port show pci/0033:01:00.0/163840
 pci/0033:01:00.0/163840: type eth netdev eth1 flavour pcisf controller 1 pfnum 0 sfnum 77 external true splittable false
