[totem] Fix Eject menu item not being available for DVDs

[Bastien Nocera <hadess src gnome org>]

commit c2ca1cb46e8f72c5bd483ff013d034f9874d6a02

    Fix Eject menu item not being available for DVDs
    
    g_file_find_enclosing_mount() on the root directory for the disc
    would find the root mount, instead of the DVD mount, and, when
    playing the DVD from the menu, the device node path is used
    instead the mount's path.
