It is not allowed to call consume_skb() from hardware interrupt context
or with interrupts being disabled. So replace dev_kfree_skb() with
dev_consume_skb_irq() under spin_lock_irqsave().

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
Signed-off-by: Yang Yingliang <yangyingliang@huawei.com>

v1 -> v2:
  Add a fix tag.
