commit 84ded2f8 upstream.

This reverts commit fe7173c2.

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.
