Subject: [PATCH] speller: do not crash by trying to free something that cannot
 be freed

Most of the returned error messages are fixed strings, not allocated
strings.

This fixes https://savannah.gnu.org/bugs/?56188.
Reported-by: Aliaksei Sakovets <alexeysakovets@gmail.com>

Bug existed since version 4.1, commit f645009a.
