Use round() instead of ceil() in calculation of a2dp vol slider position

The avrcp MESSAGE_VOLUME_CHANGED requests volumes in the range 0-127. In
convertToAudioStreamVolume() this value is scaled to a (typically much
smaller, e.g. 0-15) integer value representing the volume slider step to
be presented in the UI. Depending on the resolution in the volume
requests from the a2dp device and the resolution of the UI volume
slider, some of the requested volumes might be mapped onto the same
UI slider positions. If ceil() is exchanged for round() in
convertToAudioStreamVolume() the problem with double mapped volumes
vanishes in most realistic cases.
