【Magic V2/Honor70Pro】Miracast投屏失败100%

环境准备：
准备一台支持接受Miracast投屏的设备，并且将认证方式设置为PIN码（手机输入PIN码， Miracast Sink设备显示PIN码）。

问题复现：

1， 打开Honor 70Pro无线投屏功能 (本帖以Honor 70Pro为例，实测Magic V2也能复现)
2，搜索事先准备好的投屏Sink端设备，并发起投屏

问题表现：

输入PIN码的对话框弹出后，迅速消失。同时弹出错误提示，“HONOR 70 Pro正在使用无线投屏，暂不支持同时使用”。
详情参见附件视频


问题分析：

问题复现后，adb搜集Honor 70 Por日志，如下发现：


1, P2P链路层面的Provison Request和Provison Response协商是正常的。
2, supplicant上报P2P-PROV-DISC-ENTER-PIN事件到Framework后，Framework作出业务决策，取消当前投屏连接

Magic V2/Honor70Pro 配合普通Windows笔记本电脑PIN码投屏，也会投屏失败！！！
