Log:
  Don't bother retrying errors for encrypted drives that are locked.
  
  sys/cam/scsi/scsi_all.c:
  	In the asc_table, if we get a 0x20,0x02 error ("Access denied -
  	no access rights"), don't bother retrying.  Instead, immediately
  	fail the command.
  
  	This is the error returned by Self Encrypting Drives (SED) when
  	they are locked.
