kdc: Add ret to common svc req elements

Browse Source 
We're logging SUCCESS even when the KDC sends error replies.  That's
because we're returning success to process_request() even when we send
errors to clients.  The error we want to send to the client, and that we
succeed or fail to send it, are different statuses.

Also, further move things into `r` and out of function arguments.
