Yu Kuai fa2bbff7b0 md: synchronize flush io with array reconfiguration 
Currently rcu is used to protect iterating rdev from submit_flushes():

submit_flushes			remove_and_add_spares
				synchronize_rcu
				pers->hot_remove_disk()
 rcu_read_lock()
 rdev_for_each_rcu
  if (rdev->raid_disk >= 0)
				rdev->radi_disk = -1;
   atomic_inc(&rdev->nr_pending)
   rcu_read_unlock()
   bi = bio_alloc_bioset()
   bi->bi_end_io = md_end_flush
   bi->private = rdev
   submit_bio
   // issue io for removed rdev

Fix this problem by grabbing 'acive_io' before iterating rdev, make sure
that remove_and_add_spares() won't concurrent with submit_flushes().
