[Tarantool-patches] [PATCH v3 2/4] http: remove redundant & incorrect case for curl_request code

[Ilya Kosarev <i.kosarev@tarantool.org>]

After executing curl request we need to process curl_request code. It
might be CURL_WRITE_ERROR. We had special case for it, which assumed
diagnostic being set and contained corresponding assert, though it is
incorrect. Better way is to handle it as any other non-standard event.
