patch 8.2.4795: 'cursorbind' scrolling depends on whether 'cursorline' is set

Commit: https://github.com/vim/vim/commit/2c645e8b00641f504072f35e061b7392ed41f491
Author: Christian Brabandt <cb@256bit.org>
Date:   Wed Apr 20 14:52:01 2022 +0100

    patch 8.2.4795: 'cursorbind' scrolling depends on whether 'cursorline' is set

    Problem:    'cursorbind' scrolling depends on whether 'cursorline' is set.
    Solution:   Always call validate_cursor(). (Christian Brabandt, closes https://github.com/vim/vim/issues/10230,
                closes #10014)
