We may get SLEEP event from firmware even if TXDone interrupt for last Tx packet is still pending. In this case, we may end up accessing PCIe memory for handling TXDone after power save handshake is completed. This causes kernel crash with external abort. This patch will only allow downloading sleep confirm when no tx done interrupt is pending in the hardware.
