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: 9238f36a5a50 ("Bluetooth: Add request cmd_complete and cmd_status functions") Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
