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

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

[ Upstream commit 39c1eb6fcbae8ce9bb71b2ac5cb609355a2b181b ]

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().
