`org-maybe-renumber-ordered-list' do not call `org-fix-bullet-type'.

* org-list.el (org-maybe-renumber-ordered-list): Removed call for
  `org-fix-bullet-type' to prevent infinite loop, and some checks
  already done in `org-renumber-ordered-list'.
* org-list.el (org-fix-bullet-type): Remove a check and call directly
