libata: Fix ATA request sense
For an ATA device supporting the sense data reporting feature set, a failed command will trigger the execution of ata_eh_request_sense if the result task file of the failed command has the ATA_SENSE bit set (sense data available bit). ata_eh_request_sense executes the REQUEST SENSE DATA EXT command to retrieve the sense data of the failed command. On success of REQUEST SENSE DATA EXT, the ATA_SENSE bit will NOT be set (the command succeeded) but ata_eh_request_sense nevertheless tests the availability of sense data by testing that bit presence in the result tf of the REQUEST SENSE DATA EXT command. This leads us to falsely assume that request sense data failed and to the warning message: atax.xx: request sense failed stat 50 emask 0 Upon success of REQUEST SENSE DATA EXT, set the ATA_SENSE bit in the result task file command so that sense data can be returned by ata_eh_request_sense.
