The canonical way to represent "no error hint" is making it NULL, which
shortcuts the error() call altogether. This fixes the output by removing
the line which said just "error:", which would appear when starting a
rebase whose initial checkout worked fine despite a dirty worktree. This
was introduced by 97e1873 (rebase -i: rewrite complete_action() in C,
2018-08-28), which did a somewhat inaccurate conversion from shell.
To avoid that such bugs re-appear, test for the condition in
require_clean_work_tree().
