net: plip: don't call kfree_skb/dev_kfree_skb() under spin_lock_irq()
[ Upstream commit 7d8c19bfc8ff3f78e5337107ca9246327fcb6b45 ]
It is not allowed to call kfree_skb() or consume_skb() from
hardware interrupt context or with interrupts being disabled.
So replace kfree_skb/dev_kfree_skb() with dev_kfree_skb_irq()
and dev_consume_skb_irq() under spin_lock_irq().
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
