Bluetooth: btusb: don't call kfree_skb() under spin_lock_irqsave()

[ Upstream commit 18b971db394781214aa1060789557dfbe32ca015 ]

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().
