patch 9.2.0591: 'scrolljump' ignored when scrolling up

patch 9.2.0591: 'scrolljump' ignored when scrolling up

Problem: srolljump=-100 only scrolls half a page going up, but works
fine going down. update_topline() always falls back to
scroll_cursor_halfway() when the cursor is far above topline.
Solution: Only center when sj is smaller than half the window. Otherwise
call scroll_cursor_top like the downward path does (glepnir).

fixes: #1527
closes: #20366
