[vala/staging: 1/3] gdbus: Initialize intermediate variables

[Rico Tzschichholz <ricotz src gnome org>]

commit a76cebe116ec2663ee1ee5dabc28f59477ce7993
Author: Carlos Garnacho <carlosg gnome org>
Date:   Sun Feb 12 23:08:12 2017 +0100

    gdbus: Initialize intermediate variables
    
    Those may be left uninitialized after error handling paths are introduced,
    so invalid data might be attempted to be freed later on.
