scsi: scsi_transport_sas: Fix the maximum channel scanning issue
After commit 37c4e72b0651 ("scsi: Fix sas_user_scan() to handle wildcard
and multi-channel scans"), if the device supports multiple channels (0 to
shost->max_channel), user_scan() invokes updated sas_user_scan() to perform
the scan behavior for a specific transfer. However, when the user
specifies shost->max_channel, it will return -EINVAL, which is not
expected.
Fix and support specifying the scan shost->max_channel for scanning.
