Revert "libata-eh: Set 'information' field for autosense"
commit fe16d4f202c59a560533a223bc6375739ee30944 upstream.
This reverts commit a1524f226a02aa6edebd90ae0752e97cfd78b159.
As implemented, ACS-4 sense reporting for ATA devices bypasses error
diagnosis and handling in libata degrading EH behavior significantly.
Revert the related changes for now.
