Subject: [PATCH] rcutorture: Print out barrier error as document says

Test for rcu_barrier() has introduced by commit fae4b54f28f0 ("rcu:
Introduce rcutorture testing for rcu_barrier()").  Updated document says
that `rtbe` field of output indicates failure of the test.  However, the
code has not updated as so.  This commit updates the code to print out
the field as document says.
