[ Upstream commit 8f458f783dfbb19c1f1cb58ed06eeb701f52091b ]
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: 166d2f6a4332 ("[Bluetooth] Add UART driver for Texas Instruments' BRF63xx chips")
