KYRA: Don't restore music volume right after it has faded down

Since the music volume is set in playTrack(), it shouldn't be
necessary to set it back to the default level when a fade out has
been completed.

This change prevents the volume from spiking right before quitting
the game. I hope it doesn't cause regressions.
