Eric DumazetandJakub Kicinski 26b8986a18 net: clear skb->sk in skb_release_head_state() 
skb_release_head_state() inlines skb_orphan().

We need to clear skb->sk otherwise we can freeze TCP flows
on a mostly idle host, because skb_fclone_busy() would
return true as long as the packet is not yet processed by
skb_defer_free_flush().

Fixes: 1fcf572211 ("net: allow skb_release_head_state() to be called multiple times")
Fixes: e20dfbad8a ("net: fix napi_consume_skb() with alien skbs")
