Bluetooth: hci_qca: 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: 0ff252c1976d ("Bluetooth: hciuart: Add support QCA chipset for UART")
