rcutorture: Print only one rtort_pipe_count splat

The rcu_torture_writer() function scans the memory blocks after a stutter
(or forced idle) interval, complaining about any that have not passed
through ten grace periods since the start of the stutter interval.
But one splat suffices, so this commit therefore stops at the first splat.
