devices: fix issue of per_interface_next_index
Per interface, next hop graph node can be customized with vnet_hw_interface_rx_redirect_to_node function, but it doesn't work well for af-packet type interface. In current implementation, with function af_packet_set_interface_next_node invoked next hop graph node index can be set to apif->per_interface_next_index, but it's not set to next0 properly for packet processing in af_packet_device_input_fn.
