rgw: when failing read from client, return correct errorwip-6214

Fixes: #6214
Backport: bobtail, cuttlefish, dumpling
When getting a failed read from client when putting an object
we returned the wrong value (always 0), which in the chunked-
upload case ended up in assuming that the write was done
successfully.
