For the case where an NFSv4.1 ExchangeID operation has the client identifier
that already has a confirmed ClientID, the nfsrv_setclient() function would
not fill in the clientidp being returned. As such, the value of ClientID
returned would be whatever garbage was on the stack.
This patch fixes the problem by filling in these fields.
