wifi: libertas: cmdresp: don't call kfree_skb() under spin_lock_irqsave()
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: f52b041aed77 ("libertas: Add spinlock to avoid race condition")
