[gtk+] Remove useless get_iter_at_line calls.

[Paolo Borelli <pborelli src gnome org>]

commit 7f301cf8222195ec5b45f03b7a23e8340c664737

    Remove useless get_iter_at_line calls.
    
    No need to call _gtk_text_btree_get_iter_at_line right before calling
    totally_invisible_line, since it is the first thing it does itself.
