When the event queue is full of phy up and down events and reached the threshold, we will queue a shutdown-event, and set phy->in_shutdown so that we will not queue a shutdown-event again. But before the shutdown-event can be executed, every phy-down event will clear phy->in_shutdown and a new shutdown-event will be queued. The queue will be full of these shutdown-events. Fix this by only clear phy->in_shutdown in sas_phye_shutdown(), that is after the first shutdown-event has been executed.
