mptsas: fix depth param in scsi_track_queue_full

A user of scsi_track_queue_full should pass to the function a constant value
untill the queue-depth changes, otherwise the internal logic in
scsi_track_queue_full rejects the change.  Other users of this function use a
'sdev->queue_depth - 1' as depth parameter, let's do the same.
