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