Sebastian Andrzej Siewior f37ad91270 netfilter: nf_dup_netdev: Move the recursion counter struct netdev_xmit ...

nf_dup_skb_recursion is a per-CPU variable and relies on disabled BH for its
locking. Without per-CPU locking in local_bh_disable() on PREEMPT_RT
this data structure requires explicit locking.

Move nf_dup_skb_recursion to struct netdev_xmit, provide wrappers.
