[gparted] Small simplification of Win_GParted code which calls get_custom_text()

[Curtis Gedak <gedakc src gnome org>]

commit 9ced6b051e132da39b441600fc0ecda5971bf8e4

    Small simplification of Win_GParted code which calls get_custom_text()
    
    Avoid long lines, long statements and repeated calls to
    gparted_core.get_filesystem_object( selected_partition.filesystem ) by
    storing the returned pointer in a local variable.
    
    Needs the previous commit so that the the local variable can be a
    pointer to a const FileSystem object instead of a pointer to a
    (modifiable) FileSystem object.
