patch 9.1.0643: terminal: cursor may end up on invalid position

Browse Source 
Problem:  terminal: cursor may end up on invalid position after reducing
          the scrollback lines (user202729)
Solution: After reducing the scrollback size, check the cursor position,
          making sure it does not end up on an invalid line

fixes: #15351
