winbind: Retry after SESSION_EXPIRED error in ping-dc

Browse Source 
Trying to establish a netlogon connection when the service ticket
expires might fail with NT_STATUS_NETWORK_SESSION_EXPIRED. The
underlying client code already marks the session as invalid, so retry
the netlogon connect in this case.
