Subject: [PATCH rcu 2/8] torture: Distinguish kthread stopping and being asked to stop

Right now, if a given kthread (call it "kthread") realizes that it needs
to stop, "Stopping kthread" is written to the console.  When the cleanup
code decides that it is time to stop that kthread, "Stopping kthread
tasks" is written to the console.  These two events might happen in
either order, especially in the case of time-based torture-test shutdown.

But it is hard to distinguish these, especially for those unfamiliar with
the torture tests.  This commit therefore changes the first case from
"Stopping kthread" to "kthread is stopping" to make things more clear.
