device: Don't call set_state for external device in device_claim

The function set_state disable is not called for external devices in device_release
which means for external vlan/macvlan devices they won't be deleted.
As a result of this the set_state enable call for external devices by device_claim fails
as vlan/macvlan devices cannot be created since the device already exists in the kernel.
Therefore move the external device check from device_set_state to device_claim so
external vlan/macvlan devices are not created again and can also be external.
