emacs-27 452d776: Fix small bug in copy_string_contents.

[Philipp Stephani]

branch: emacs-27
commit 452d776a5da3f25ec1ce3a632c5df8db80b507ef
Author: Philipp Stephani <address@hidden>
Commit: Philipp Stephani <address@hidden>

    Fix small bug in copy_string_contents.
    
    * src/emacs-module.c (module_copy_string_contents): Fix incorrect
    variable use.  In this branch 'lisp_str_utf8' is always nil, so it
    makes little sense to add it as error data.
