net_sched: make room for (struct qdisc_skb_cb)->pkt_segs

Browse Source 
Add a new u16 field, next to pkt_len : pkt_segs

This will cache shinfo->gso_segs to speed up qdisc deqeue().

Move slave_dev_queue_mapping at the end of qdisc_skb_cb,
and move three bits from tc_skb_cb :
- post_ct
- post_ct_snat
- post_ct_dnat
