[PATCH] rcu: Avoid kthread_stop on invalid pointer if rcutorture reader startup fails

rcu_torture_init kmallocs the array of reader threads, then creates each
one with kthread_run, cleaning up with rcu_torture_cleanup if this fails.
rcu_torture_cleanup calls kthread_stop on any non-NULL pointer in the
array; however, any readers after the one that failed to start up will have
invalid pointers, not null pointers.  Avoid this by using kzalloc instead.
