AudioService: fix deadlock between readSettings() and VSS.setAllIndexes()

Locking order is mSettingsLock -> VolumeStreamState.class
Missing sync on mSettingsLock was causing deadlock between
  VolumeStreamState.setAllIndexes() and readSettings().
Mark that setAllIndexesToMax() is properly sync'd on mSettingsLock.
