In case of alive interrupt timeout or any failure in the init flow the driver generates FW nmi. The driver assumes that the nmi will generate SW interrupt. This assumption does not hold and leads to faulty behavior in the recovery flow. Solve this by using sync nmi, this way, even if the driver does not receive SW interrupt, it still starts the recovery flow. Also remove the wait queue from iwl_fwrt_stop_device since the driver is handling the SW interrupt synchronously.
