Revert "libata: Implement NCQ autosense"

commit 74a80d67b8316eb3fbeb73dafc060a5a0a708587 upstream.

This reverts commit 42b966fbf35da9c87f08d98f9b8978edf9e717cf.

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.
