This reverts commit 2567f8020e. It assumes
that assembling logic could break some failover scenarios if request
forwarding is done. However, it also breaks requesting big objects via a
non-container node with TTL=2. Failover has been rechecked without that
commit and no problems were found. Any (if found) other bugs related to
the forwarding and object assembling must be solved more carefully.
