From: Fred Isaman <iisaman@xxxxxxxxxxxxxx>
clp->cl_exchange_flags is used both for client output and server input.
This causes problems in certain recovery situations, when the server
has sent back EXCHGID4_FLAG_CONFIRMED_R, causing the client to erroneously
use the flag in future EXCHANGE_ID requests.
