[libata] Prevent interface errors with Seagate FreeAgent GoFlex
When using my Seagate FreeAgent GoFlex eSATAp external disk enclosure,
interface errors are always seen until 1.5Gbps is negotiated [1]. This
occurs using any disk in the enclosure, and when the disk is connected
directly with a generic passive eSATAp cable, we see stable 3Gbps
operation as expected.
Blacklist 3Gbps mode to avoid dataloss and the ~30s delay bus reset
and renegotiation incurs.
