Merge pull request !338 from phchang/rwlock

【背景】修复rwlock门禁用例多次测试出现的程序会卡死在某一个地方的问题，经查找程序会卡在循环里面

【修改方案】
1.经测试，发现用例在创建线程后对退出标志位做了初始化，但卡在循环中不动的原因是在创建线程后立刻发生了调度，没有来得及初始化，则发生了错误，故会出现卡在循环中的情况。
而且，由于卡在循环中时线程是同一优先级，可能不会发生调度，故在循环里面加了一句可以调度的语句，防止在一处循环卡的太久。
2.将该用例挪出门禁，待稳定后恢复。
【影响】
对其它用例无影响。

内存完整性校验原有逻辑中当检测到非零异常指针后仍继续访问异常指针
next的内存域导致系统异常。
本次修改后的逻辑为：检测到非零异常指针后直接退出循环，将异常指针
的相关信息输出即可，增加了goto逻辑。对原有功能逻辑无影响。
