patch 9.1.1238: wrong cursor column with 'set splitkeep=screen'
Problem: With ':set splitkeep=screen', cursor did't restore column
correctly when splitting a window on a line longer than the
last line on the screen (after v9.1.0707)
Solution: Restore cursor column in `win_fix_scroll()` since it may be
changed in `getvcol()` after 396fd1ec2956 (phanium).
Example:
```
echo longlonglongling
short | vim - -u NONE --cmd 'set
splitkeep=screen' +'norm $' +new +q
```
fixes: #16968
closes: #16971
