Merge branch 'net-skb-defer-freeing-polish'

Eric Dumazet says:

====================
net: polish skb defer freeing

While testing this recently added feature on a variety
of platforms/configurations, I found the following issues:

1) A race leading to concurrent calls to smp_call_function_single_async()

2) Missed opportunity to use napi_consume_skb()

3) Need to limit the max length of the per-cpu lists.

4) Process the per-cpu list more frequently, for the
   (unusual) case where net_rx_action() has mutiple
   napi_poll() to process per round.
====================
