Before "msm: SSR: Pull struct restart_wq_data into struct subsys_device" we would allocate a work struct for every instance of a subsystem_restart() call. After that change, we only allocate one instance of the work during intialization and we serialize calls to queue_work() with a restarting flag in the subsys_device structure. This has the unfortunate side effect of silently ignoring a subsystem_restart() call made while a subsystem is in the process of restarting (i.e. hasn't reached the end of subsystem_restart_wq_func(). Add a refcount around the wake lock so that the system stays out of suspend for as long as any restart work item is being processed. Then queue the work unconditionally so that the work queue function can determine that a subsystem restart is happening while the subsystem is powering up.
