Clean up UserMediaCaptureManagerProxy.cpp

[Peng Liu]

In UserMediaCaptureManagerProxy.cpp

void audioUnitWillStart() final
{
    // FIXME: WebProcess might want to set the category/bufferSize itself, in which case we should remove that code.
    auto bufferSize = AudioSession::sharedSession().sampleRate() / 50;
    if (AudioSession::sharedSession().preferredBufferSize() > bufferSize)
        AudioSession::sharedSession().setPreferredBufferSize(bufferSize);
    AudioSession::sharedSession().setCategory(AudioSession::PlayAndRecord, RouteSharingPolicy::Default);
}

Probably we need to remove this code section now?

Hum, in case of GPUProcess crash, we would need to ensure the audio session category is set before restarting audio capture.
There is no such guarantee right now.
