[PATCH tip/core/rcu 3/5] rcutorture: Print out barrier error as document says

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

From: SeongJae Park <sj38.park@gmail.com>

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.
