nfp: don't advertise hw-tc-offload on non-port netdevs
nfp_port is a structure which represents an ASIC port, both PCIe vNIC (on a PF or a VF) or the external MAC port. vNIC netdev (struct nfp_net) and pure representor netdev (struct nfp_repr) both have a pointer to this structure. nfp_reprs always have a port associated. nfp_nets, however, only represent a device port in legacy mode, where they are considered the MAC port. In switchdev mode they are just the CPU's side of the PCIe link. By definition TC offloads only apply to device ports. Don't set the flag on vNICs without a port (i.e. in switchdev mode).
