bug描述：当使用revoke，grant命令收回，授予权限出错时（语法错误除外），会导致主从同步异常终止。如：
mysql> revoke select on *.* from aaa;
ERROR 1141 (42000): There is no such grant defined for user ‘aaa‘ on host ‘%‘ 该用户没有该权限却执行了回收该权限
mysql> GRANT FILE ON test.* TO [email protected];
ERROR 1221 (HY000): Incorrect usage of DB GRANT and GLOBAL PRIVILEGES 错误授权等
影响版本：mysql 5.6~5.6.13
场景重现：
master：
mysql> insert into a values(1);
Query OK, 1 row affected (0.00 sec)
mysql> GRANT FILE ON test.* TO [email protected];
ERROR 1221 (HY000): Incorrect usage of DB GRANT and GLOBAL PRIVILEGES
mysql> insert into a values(2);
Query OK, 1 row affected (0.00 sec)
mysql> insert into a values(3);
Query OK, 1 row affected (0.00 sec)
slave：
mysql> show slave status\G
