the skbs can be held by the driver for a long time, so we need to clear any state on xmit to avoid hanging other subsystems. The skbs are already orphaned and dsts are dropped, later in ib/cm code, so we just need to clear the nf state. Do it early, while the ct entry is hopefully still hot in the cache.
