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

Browse source 
[ Upstream commit df4cfc91208e0a98f078223793f5871b1a82cc54 ]

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().
