[ Upstream commit f393df151540bf858effbd29ff572ab94e76a4c4 ]
It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. So replace kfree_skb()
with dev_kfree_skb_irq() under spin_lock_irqsave(). Compile
tested only.
Fixes: d2e7b3425c47 ("libertas: disable functionality when interface is down")
