vim-patch:9.1.1216: Pasting the '.' register multiple times may not work

Problem:  Pasting the '.' register multiple times may work incorrectly
          when the last insert starts with Ctrl-D and ends with '0'.
          (after 9.1.1212)
Solution: Restore the missing assignment (zeertzjq).

closes: vim/vim#16908
