[SCSI] Make scsi_scan_host work for drivers which find their own targets
If a driver can find its own targets, it can now fill in scan_finished and
(optionally) scan_start in the scsi_host_template. Then, when it calls
scsi_scan_host(), it will be called back (from a thread if asynchronous
discovery is enabled), first to start the scan, and then at intervals to
check if the scan is completed.
Also make scsi_prep_async_scan and scsi_finish_async_scan static.
