rcutorture: Use atomic increment for n_rcu_torture_timers

Currently, rcu_torture_timer() relies on a lock to guard updates to
n_rcu_torture_timers.  Unfortunately, consolidating code with
rcu_torture_reader() will dispense with this lock.  This commit
therefore makes n_rcu_torture_timers be an atomic_long_t and uses
atomic_long_inc() to carry out the update.
