Currently C-h K (Info-goto-emacs-key-command-node) throws an error when
used on anonymous commands, for example:

1. emacs -Q
2. Evaluate this form:
    (keymap-global-set "C-c m"
                       (lambda ()
                         (interactive)
                         (message "foo")))
3. Type C-h K C-c m
4. Get this error:
    Info-goto-emacs-command-node: Wrong type argument: symbolp, (closure (t) nil (interactive) (message "foo"))

This patch makes Info-goto-emacs-key-command-node detect and handle such
cases by printing an informative message instead of calling
Info-goto-emacs-command-node.
