qeth: set lan_online flag after a received STARTLAN

Problem:     A STARTLAN command from the adapter may arrive while a
             qeth recovery is currently running with a failed qeth
             STARTLAN. Usually qeth schedules a recovery when
             receiving a STARTLAN command from the adapter. But
             another recovery scheduled while a recovery is already
             running never starts. Thus the qeth-administered
             lan_online flag remains zero in this scenario, even
             though the adapter-STARTLAN has happened.
Solution:    Set lan_online flag for a received STARTLAN from the
             adapter in case scheduled recovery does not start.
