Revert "libata: Implement support for sense data reporting"
This reverts commit fe7173c206de63fc28475ee6ae42ff95c05692de. 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. ATA_ID_COMMAND_SET_3/4 constants are not reverted as they're used by later changes. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Hannes Reinecke <hare@suse.de> Cc: stable@vger.kernel.org #v4.1+
