rcutorture: ASSERT_EXCLUSIVE_WRITER() for ->rtort_pipe_count updates

Browse source

It turns out that only one CPU at a time will ever invoke
rcu_torture_pipe_update_one() on a given rcu_torture structure.
This commit therefore adds three ASSERT_EXCLUSIVE_WRITER() calls
to enlist KCSAN's aid in checking this.
