This patch invokes RECLAIM_COMPLETE after the client is done
reclaiming state.

There are interpretations of the spec that suggest that
RECLAIM_COMPLETE should also be issued after a new clientid
has been obtained from the server and even if there is no
state to reclaim.  This tells the server that the client
has no state to reclaim even if the client isn't aware the
server may have rebooted.
