Subject: libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8

From: Michele Baldessari <michele@xxxxxxxxxx>

commit 87809942d3fa60bafb7a58d0bdb1c79e90a6821d upstream.

We've received multiple reports in Fedora via (BZ 907193)
that the Seagate Momentus SpinPoint M8 errors out when enabling AA:
[    2.555905] ata2.00: failed to enable AA (error_mask=0x1)
[    2.568482] ata2.00: failed to enable AA (error_mask=0x1)

Add the ATA_HORKAGE_BROKEN_FPDMA_AA for this specific harddisk.
