Bluetooth: hci_core: 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: 9238f36a5a ("Bluetooth: Add request cmd_complete and cmd_status functions")
