Currently, the .exp_hint flag is cleared in rcu_read_unlock_special(), which works, but which can also prevent subsequent rcu_read_unlock() calls from helping expedite the quiescent state needed by an ongoing expedited RCU grace period. This commit therefore defers clearing of .exp_hint from rcu_read_unlock_special() to rcu_preempt_deferred_qs_irqrestore(), thus ensuring that intervening calls to rcu_read_unlock() have a chance to help end the expedited grace period.
