scsi: libsas: only clear phy->in_shutdown after shutdown event done
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.
Fixes: f12486e06ae8 ("scsi: libsas: shut down the PHY if events reached the threshold")
