[PATCH net] net: dlink: sundance: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

[Yang Wei]

From: Yang Wei <yang.w...@zte.com.cn>

dev_consume_skb_irq() should be called in intr_handler() when skb
xmit done. It makes drop profiles(dropwatch, perf) more friendly.

Remove a redundant blank line in intr_handler().
