Ranjan Kumar 37c4e72b06 scsi: Fix sas_user_scan() to handle wildcard and multi-channel scans
sas_user_scan() did not fully process wildcard channel scans
(SCAN_WILD_CARD) when a transport-specific user_scan() callback was
present. Only channel 0 would be scanned via user_scan(), while the
remaining channels were skipped, potentially missing devices.

user_scan() invokes updated sas_user_scan() for channel 0, and if
successful, iteratively scans remaining channels (1 to
shost->max_channel) via scsi_scan_host_selected().  This ensures complete
wildcard scanning without affecting transport-specific scanning behavior.
