NFSv4.1: CB_RECALL_SLOT must schedule a sequence op after updating targets
RFC5661 requires us to make sure that the server knows we've updated our slot table size by sending at least one SEQUENCE op containing the new 'highest_slotid' value. We can do so using the 'CHECK_LEASE' functionality of the state manager. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
