From: Alexander Graf <ag...@suse.de>
When using Windows 8 with an AHCI disk drive, it issues a blue screen.
The reason is that WIN_SECURITY_FREEZE_LOCK / CFA_WEAR_LEVEL is not
supported by our ATA implementation, but Windows expects it to be there.
Since without security stuff implemented, the lock would be a nop anyway
and CFA_WEAR_LEVEL already is treated as a nop, let's just allow the cmd
for HD drives as well. That way Windows is happy.
