The ->rcu_read_unlock_special.b.deferred_qs field is set to true in rcu_read_unlock_special() but never set to false. This is not particularly useful, so this commit removes this field. The only possible justification for this field is to ease debugging of RCU deferred quiscent states, but the combination of the other ->rcu_read_unlock_special fields plus ->rcu_blocked_node and of course ->rcu_read_lock_nesting should cover debugging needs. And if this last proves incorrect, this patch can always be reverted, along with the required setting of ->rcu_read_unlock_special.b.deferred_qs to false in rcu_preempt_deferred_qs_irqrestore().
