rustdoc-search: remove the now-redundant `validateResult`

This function dates back to 9a45c9d7c6928743f9e7a7161bf564a65bfc0577 and
seems to have been made obsolete when `addIntoResult` grew the ability to
check the levenshtein distance matching with commit
ba824ec52beb0e49b64e86837c1402a0c2d0c971.
