rcutorture: Add diagnostic for unscheduled system shutdown
Currently, rcutorture can terminate via rmmod, via self-shutdown, via something else shutting the system down, or of course the usual catastrophic termination. The first two get flagged, so this commit adds a message for the third. For the fourth, your warranty is void as always. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org>
