bonding: graph node running after bond-input in feature arc may crash

In bond RX quad loop, when all packets within the frame have the same incoming
interface, we cannot skip calling bond_update_next because that function calls
vnet_feature_next() to update the b->current_config_index. The next node needs
the correct b->current_config_index to work with.

Type: fix
