rcutorture: Add missing destroy_timer_on_stack()
The rcu_torture_reader() function uses an on-stack timer_list structure which it initializes with setup_timer_on_stack(). However, it fails to use destroy_timer_on_stack() before exiting, which results in leaking a tracking object if DEBUG_OBJECTS is enabled. This commit therefore invokes destroy_timer_on_stack() to avoid this leakage.
