setAvrcpAbsoluteVolume is passed wrong unit parameter from AudioManager

setAvrcpAbsoluteVolume is passed wrong unit parameter from AudioManager.
It cause maximize volume in Bluetooth speaker/device.
The volume expected by Bluetooth Avrcp should be from 0 to 15.
But the current volume parameter passed to Bluetooth Avrcp is from 0 to 150.
It is scaled by 10 times than the correct volume.
index = rescaleIndex(index * 10, streamType, streamTypeAlias);
Should divide the volume by 10 before pass to Bluetooth Avrcp.
