[PATCH #upstream-fixes] libata: OCZ Vertex can't do HPA

[Tejun Heo]

OCZ Vertex SSD can't do HPA and not in a usual way.  It reports HPA,
allows unlocking but then fails all IOs which fall in the unlocked
area.  Quirk it so that HPA unlocking is not used for the device.

Reported by Daniel Perup in bnc#522414.
