Bug - AOSP Volume panel - Wrong volume after rotate.

Root cause :
voice call and bluetooth are not inaudible. So volume and max will +1 in onVolumeChanged. for these 2 streams.  When orientation changed, it doesn't +1 in the seekbar cause this problem.

Solution :  As below call stack, +1 on volume for these 2 streams in updateSlider.
