org-footnote: Don't offer to create a footnote when it already exists

Browse Source 
* lisp/org-footnote.el (org-footnote-goto-definition): This patch
  makes sure the function says when a definition has been found.
  Thus, moving from the reference to the definition doesn't offer to
  create the latter again.
