scsi: Add 'hba_private' to SCSIRequest
'tag' is just an abstraction to identify the command from the driver. So we should make that explicit by replacing 'tag' with a driver-defined pointer 'hba_private'. This saves the lookup for driver handling several commands in parallel. 'tag' is still being kept for tracing purposes.
