Unfortunately, it's not quite right.  The line of code in question needs to be

if ((vstor_packet->vm_srb.scsi_status & 0xFF) == SAM_STAT_CHECK_CONDITION &&

The status_byte() helper was doing the masking as well as the right shift, so the
masking will need to be open coded.  The replacement get_status_byte() helper 
won't work here because it's based on a scsi_cmnd structure.
