The rcu_tasks_percpu structure's->lazy_timer is queued only when
the rcu_tasks structure's->lazy_jiffies is not equal to zero in
call_rcu_tasks_generic(), if the lazy_timer callback is invoked,
that means the lazy_jiffes is not equal to zero, this commit
therefore remove lazy_jiffies check in call_rcu_tasks_generic_timer().
