When we switched off CURLOPT_FAILONERROR in 17966c0a (http: avoid
disconnecting on 404s for loose objects, 2016-07-11), the fetch_object()
function started manually handling 404's. Since we now have
normalize_curl_result() for use elsewhere, we can use it here as well,
shortening the code.

Note that we lose the check for http/https in the URL here. None of the
other result-normalizing code paths bother with this. Looking at
missing_target(), which checks specifically for an FTP-specific CURLcode
and "http" code 550, it seems likely that git-over-ftp has been subtly
broken since 17966c0a

. This patch does nothing to fix that, but nor
should it make anything worse (in fact, it may be slightly better
because we'll actually recognize an error as such, rather than assuming
CURLE_OK means we actually got some data).
