Yang Yingliang b242358a27 net: ethernet: dnet: don't call dev_kfree_skb() under spin_lock_irqsave() ...

[ Upstream commit f07fadcbee2a5e84caa67c7c445424200bffb60b ]

It is not allowed to call kfree_skb() or consume_skb() from hardware
interrupt context or with hardware interrupts being disabled.

In this case, the lock is used to protected 'bp', so we can move
dev_kfree_skb() after the spin_unlock_irqrestore().
