qcacld-3.0: Prevent access to rx thread after thread shutdown During unload/SSR, the ol_rx_thread is shutdown and then the cpu hotplug notifier is unregistered. In other context cpu hotplug notifier could be accessing the freed contents of rxthread resulting in use after free. To avoid this race condition, reject the cpu hot plug notificaiton in case of a driver SSR in addition to load/unload. Change-Id: Iafadff92d5660b979c6cf20a70eef42d22a9e51a CRs-Fixed: 2219011
