[Android] Fix the issue of muted attribute in video element does not work.

[Android] Fix the issue of muted attribute in video element does not work.

SetVolume is called before the media player bridge is created, so the
volume(muted) is not set correctly.

The player could get destroyed if releaseMediaResources is called. The correct
implementation should use a member variable to store the volume here, and call
the jni function when java mediaplayer is created.
Check the implementation in media_source_player.cc

Hi qinmin, patch updated by using member variable to store volume, thanks for
review.
