Bluetooth: hci_ll: don't call kfree_skb() under spin_lock_irqsave()
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")
