Currently, there might be a scenario where wlan host driver calls idle_shutdown and at the same time icnss driver receives shutdown notification for wpss. In this case Race condition might occur for is_ssr variable which is shared among icnss_wpss_notifier_nb() api and icnss_idle_shutdown() api. To resolve this race condition, set is_idle_shutdown atomic variable in icnss_idle_shutdown() api and check this variable before posting ICNSS_DRIVER_EVENT_UNREGISTER_DRIVER event.
