scsi: nsp32: Stop using the SCSI pointer

Move the SCSI status field to private data. Stop setting the .ptr,
.this_residual, .buffer and .buffer_residual SCSI pointer members
since no code in this driver reads these members.

This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.
