Modified checkAndSetVolume() method to adjust VOICE_CALL, BLUETOOTH_SCO and DTMF stream volumes to match audio hardware behavior (never 0).
Also do the following adjustments on stream volumes:
- VOICE_CALL:
	if in call, force software volume to max to avoid applying the volume twice (software mixer + audio hardware)
	send setVoiceVolume() to set in call volume in audio hardware
- BLUETOOTH_SCO:
	send setVoiceVolume() with max value because volume is applied by BT headset and should not be also applied by audio hardware.
- DTMF:
	if in call and not using the BT SCO device, force software volume to max to avoid applying the volume twice (software mixer + audio hardware)
