Shoosh byte-compilation warning in lisp/emacs-lisp/eldoc.el

Per bug#43609, elisp-eldoc-documentation-function is again in master,
but since it's now officially obsoleted, this backward compatibility
shim in eldoc--eval-expression-setup shouldn't unnecessarily trigger
warnings in master's code.

* lisp/emacs-lisp/eldoc.el (eldoc--eval-expression-setup): Shoosh
by-compilation warning.
