Merge branch 'net-dev_kfree_skb_irq'

Yang Yingliang says:

====================
net: don't call dev_kfree_skb() under spin_lock_irqsave()

It is not allowed to call consume_skb() from hardware interrupt context
or with interrupts being disabled. This patchset replace dev_kfree_skb()
with dev_kfree_skb_irq/dev_consume_skb_irq() under spin_lock_irqsave()
in some drivers, or move dev_kfree_skb() after spin_unlock_irqrestore().

v2 -> v3:
  Update commit message, and change to use dev_kfree_skb_irq() in patch #1, #3.

v1 -> v2:
  patch #2 Move dev_kfree_skb() after spin_unlock_irqrestore()
