Yang Yingliang 330b9e8058 Bluetooth: RFCOMM: don't call kfree_skb() under spin_lock_irqsave() 
[ Upstream commit 0ba18967d4 ]

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: 81be03e026 ("Bluetooth: RFCOMM: Replace use of memcpy_from_msg with bt_skb_sendmmsg")
