wifi: libertas: main: don't call kfree_skb() under spin_lock_irqsave()

Browse Source 
[ Upstream commit f393df1515 ]

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: d2e7b3425c ("libertas: disable functionality when interface is down")
