[SCSI] libsas: revert ata srst
libata issues follow up srsts when the controller has a hard time recording the signature-fis after a reset, or if the link supports port multipliers. libsas does not support port multipliers and no current libsas lldds appear to need help retrieving the signature fis. Revert it for now to remove confusion. Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
