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.
Type: fix
