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

Browse source

[ Upstream commit 3968e81ba6 ]

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: a3128feef6 ("libertas: use irqsave() in USB's complete callback")
