The only thing I can figure is that it was intended to give cifsd time
to come down before freeing the cifsSesInfo struct. Sounds like a racy
proposition though :-)
Now that cifsd is kthread based, we know that it's down once
kthread_stop returns. If that was the original reason, then we
definitely don't need it anymore.
