net/bonding: fix port id validity check on parsing

If the port_id is equal to RTE_MAX_ETHPORTS, it should be considered
invalid. Additionally, UNUSED ports are also not valid port ids to be
used afterward.

To simplify following the ethdev API rules, use the exposed function
checking whether a port id is valid.
