It is not allowed to call kfree_skb() or consume_skb() from hardware
interrupt context or with hardware interrupts being disabled.
It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead.
The difference between them is free reason, dev_kfree_skb_irq() means
the SKB is dropped in error and dev_consume_skb_irq() means the SKB
is consumed in normal.
In this case, dev_kfree_skb() is called in mace_tx_timeout() to drop
the SKB, when tx timeout, so replace it with dev_kfree_skb_irq().
