virtiofsd: Set req->reply_sent right after sending reply
There is no reason to set it in label "err". We should be able to set it right after sending reply. It is easier to read. Also got rid of label "err" because now only thing it was doing was return a code. We can return from the error location itself and no need to first jump to label "err".
