audio: av_bt: add replace_stream_bt_sco status check in SwAudioOutputDescriptor::setVolume

Android w introduces a new logic. When the replace_stream_bt_sco flag is true, stream_bluetooth_sco will be changed to stream_voice_call in audioservice.java. Then audiopolicy will not receive the index change of stream_bluetooth_sco, and there is no need to force the volume of stream_bluetooth_sco to be synchronized to stream_voice_call.

Bug: 403675919
Test: Make VOIP/Voice calls using spk/sco.
Flag: EXEMPT bug fix
