[gparted] Fix incorrect dmraid partition path name (#634553)

[Curtis Gedak <gedakc src gnome org>]

commit 3c35a7ff42927bfcd89465661766b661f4fbcb76

    Fix incorrect dmraid partition path name (#634553)
    
    Enhance code so that all calls to the ped_partition_get_path
    function in the libparted library go through one
    GParted_Core::get_partition_path method.
    
    This one method makes the appropriate adjustments to the dmraid
    partition path name as required.
    
    Closes bug #634553 - ntfsresize fails on RAID array
