Salyzyn, Mark 8e31e607ea [SCSI] aacraid: do not set valid bit in sense information

Point taken regarding the aacraid driver. Dropped the VALID bit, and
then did some cleanup/simplification of the set_sense procedure and
the associated parameters. Mike did some preliminary tests when the
VALID bit was dropped before the 'Re: [PATCH] [SCSI] sd: make error
handling more robust' patches came on the scene. The change in the
SCSI subsystem does make this enclosed aacraid patch unnecessary, so
this aacraid patch is merely post battle ground cleanup. If the
simplification is an issue, repugnant, too much for a back-port to the
stable trees or clouds the point, this patch could be happily
distilled down to:
