cxgb4: use dev_port to identify ports

Commit c71abc442cf3e793781cf25d221c3c9e690640bc ("net: Add sysfs file
for port number") introduce dev_port to network devices. cxgb4 adapters
have multiple ports on the same PCI function, and used dev_id to
identify those ports. That use was removed by commit
3de857a0efb514606243c7684e629d1aa704e517 ("cxgb4: Do not set
net_device::dev_id to VI index"), since dev_id should be used only when
devices share the same MAC address.

Using dev_port for cxgb4 allows different ports on the same PCI function
to be identified.
