[gtk+/places-sidebar: 211/212] Don't allow drops in unmounted volumes

[Federico Mena Quintero <federico src gnome org>]

commit 6d94f8a56c3385f1237e3be8ef20a4fb9b472636
Author: Federico Mena Quintero <federico gnome org>
Date:   Wed Feb 27 12:16:28 2013 -0600

    Don't allow drops in unmounted volumes
    
    Unmounted volumes don't have a URI yet, so we can use that to distinguish them
    from within the DnD code.
