Subject: ata_id: Fixed getting Response Code from SCSI Sense Data (#24921)
The Response Code is contained in the first byte of the SCSI Sense Data.
Bit number 7 is reserved or has a different meaning for some Response Codes
and is set to 1 for some drives.
(cherry picked from commit 2be1ae54badf7a3a12908a8094ebaba8f91887ca)
