[ Upstream commit 383630cc6758d619874c2e8bb2f68a61f3f9ef6e ]
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: 43eb12d78960 ("Bluetooth: Fix/implement Three-wire reliable packet sending")
