v6:
* 1/2 use static key and compiled when CONFIG_NET_EGRESS configured.
v5:
* 1/2 merge netdev_xmit_reset_txqueue(void),
  netdev_xmit_skip_txqueue(void), to netdev_xmit_skip_txqueue(bool skip). 
v4:
* 1/2 introduce netdev_xmit_reset_txqueue() and invoked in
  __dev_queue_xmit(), so ximt.skip_txqueue will not affect
  selecting tx queue in next netdev, or next packets.
  more details, see commit log.
* 2/2 fix the coding style, rename:
  SKBEDIT_F_QUEUE_MAPPING_HASH -> SKBEDIT_F_TXQ_SKBHASH
  SKBEDIT_F_QUEUE_MAPPING_CLASSID -> SKBEDIT_F_TXQ_CLASSID
  SKBEDIT_F_QUEUE_MAPPING_CPUID -> SKBEDIT_F_TXQ_CPUID
* 2/2 refactor tcf_skbedit_hash, if type of hash is not specified, use
  the queue_mapping, because hash % mapping_mod == 0 in "case 0:"
* 2/2 merge the check and add extack
v3:
* 2/2 fix the warning, add cpuid hash type.
v2:
* 1/2 change skb->tc_skip_txqueue to per-cpu var, add more commit message.
* 2/2 optmize the codes.
