方法名：reducePermits

Semaphore.reducePermits介绍

[英]Shrinks the number of available permits by the indicated reduction. This method can be useful in subclasses that use semaphores to track resources that become unavailable. This method differs from acquire in that it does not block waiting for permits to become available.
[中]将可用许可证的数量减少指定的数量。这种方法在使用信号量跟踪不可用资源的子类中很有用。此方法与acquire的不同之处在于，它不会阻止等待许可证可用。
