Adopt DEBUG_NET_WARN_ON_ONCE() in some places where it makes sense.

Add checks in napi_consume_skb() and __napi_alloc_skb()

Make sure napi_get_frags() does not use page fragments
for skb->head.

Eric Dumazet (8):
  net: use DEBUG_NET_WARN_ON_ONCE() in __release_sock()
  net: use DEBUG_NET_WARN_ON_ONCE() in dev_loopback_xmit()
  net: use DEBUG_NET_WARN_ON_ONCE() in inet_sock_destruct()
  net: use DEBUG_NET_WARN_ON_ONCE() in sk_stream_kill_queues()
  af_unix: use DEBUG_NET_WARN_ON_ONCE()
  net: use DEBUG_NET_WARN_ON_ONCE() in skb_release_head_state()
  net: add debug checks in napi_consume_skb and __napi_alloc_skb()
  net: add napi_get_frags_check() helper
