[PATCH v2 4/3] scftorture: Wait until scf_cleanup_handler() completes.

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

The smp_call_function() needs to be invoked with the wait flag set to
wait until scf_cleanup_handler() is done. This ensures that all SMP
function calls, that have been queued earlier, complete at this point.
