Initialize the volume seekbar preference max and progress.

Browse Source 
When the media stream is set, initialize the preference max and progress
with the streams current value. Otherwise, when we initialize the seekbar
volumizer, it will first set the seekbar max to 0 and progress to 0,
then update with the correct value, which will result in the jank that
is seen when the sound settings are displayed.
