[ Upstream commit b15a6bd3c80c77faec8317319b97f976b1a08332 ]
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().
Fixes: 803b58367ffb ("Bluetooth: btusb: Implement driver internal packet reassembly")
