dpdk: fix Unknown interface with Mellanox NIC
When port_type_from_speed_capa() is called before the port link update isn't completed,
xd->port_type becomes VNET_DPDK_PORT_TYPE_UNKNOWN. This happens with Mellanox NIC
without lsc interrupt. Calling rte_eth_link_get before getting dev_info will ensure
the link state is up-to-date.
