[PATCH net-next 02/10] net: skb: add SKB_DR_RESET

[Menglong Dong]

For now, the skb drop reason can be SKB_NOT_DROPPED_YET, which makes the
kfree_skb_reason call consume_skb. In some case, we need to make sure that
kfree_skb is called, which means the reason can't be SKB_NOT_DROPPED_YET.
Introduce SKB_DR_RESET() to reset the reason to NOT_SPECIFIED if it is
SKB_NOT_DROPPED_YET.
