wifi: ath10k: trigger hardware recovery upon rx failures

Browse source

When an error occurs during RX packet processing (e.g., MSDU done
failure), the driver sets rx_confused and drops all subsequent RX
packets until a Wi-Fi ON/OFF cycle clears the flag. This can leave
the device in a bad state where it cannot process RX data traffic.

Instead of leaving the device in such a state, trigger hardware
recovery so that such an error state can be reset and the device
can function again normally.
