AgoraAudioCriticalSection causes ios agora-ScreenShare-Exension demo to crash with EXC_BAD_ACCESS

[koogawa]

Tested on: ios 14.6, iPad Pro

Steps to reproduce:

1. Build and run APIExample demo ios app
2. Launch extension via picker in APIExample container app and start screen broadcasting.
3. Navigate to any app playing in app audio
4. Observe EXC_BAD_ACCESS crash occurring on this line.

Have observed similar behavior with mic audio as well. Seems to occur if I start the broadcast without the mic enabled and then enable the mic while the broadcast extension is running.
