参数：
Object [in]
A pointer to the body of the object.
指向对象实体的指针
返回值
None
备注：
ObDereferenceObjectDeferDelete is similar to ObDereferenceObject except that,
when the reference count of the object reaches zero,
the object manager passes the object deletion request to a worker thread.
Therefore, the deletion later occurs at IRQL = PASSIVE_LEVEL.
ObDereferenceObjectDeferDelete与ObDereferenceObject类似，除了，当引用计数为 0 时，对象管理器传递对象删除请求到工作线程。
因此，当之后IRQL=PASSIVE_LEVEL时，发生删除。

Use ObDereferenceObjectDeferDelete for any object when the immediate deletion by the current thread of the object (by using ObDereferenceObject)
might result in a deadlock.
Google翻译的，我不懂...

For example, such a deadlock can occur if ObDereferenceObject is used to dereference a Kernel Transaction Manager (KTM) object
when a higher level driver on the driver stack is holding a lock.
例如，使用ObDereferenceObject为Kernel Transaction Manager(KTM) 对象解引用 ，当一个驱动栈上的高层驱动持有锁时，会发生死锁。

To avoid such deadlocks, use ObDereferenceObjectDeferDelete instead of ObDereferenceObject to dereference KTM objects.
为了避免死锁，应使用ObDereferenceObjectDeferDelete代替ObDereferenceObject 对KTM对象解外用。
