vim-patch:9.0.1561: display wrong when moving cursor to above the top line (#23644)
Problem:    Display wrong when moving cursor to above the top line and
            'smoothscroll' is set.
Solution:   Call adjust_skipcol() in more places and make it work better.
            (Luuk van Baal, closes vim/vim#12395)
