vim-patch:9.1.1297: Ctrl-D scrolling can get stuck #33453

Problem:  cursor_correct() calculates a valid cursor position which
	  is later changed by update_topline() and causes Ctrl-D
          scrolling to be stuck (Daniel Steinberg, after v9.1.0258).
Solution: Update the valid cursor position before validating topline
          (Luuk van Baal).
