[SCSI] cleanup usages of scsi_complete_async_scans 

Now that scsi registers its async scan work with the async subsystem,
wait_for_device_probe() is sufficient for ensuring all scanning is
complete.

[jejb: fix merge problems with eea03c20ae Make wait_for_device_probe() also do scsi_complete_async_scans()]
