Subject: [PATCH net 2/4] net: ethernet: dnet: 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. So replace dev_kfree_skb() with
dev_consume_skb_irq() under spin_lock_irqsave().

Fixes: 4796417417a6 ("dnet: Dave DNET ethernet controller driver (updated)")
