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

[ Upstream commit 3968e81ba644f10a7d45bae2539560db9edac501 ]

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.
