libata: improve HPA error handling
There's no point in retrying and eventually failing device detection
when the device rejects READ_NATIVE_MAX[_EXT]. Disable HPA unlocking
if READ_NATIVE_MAX[_EXT] is rejected as done when SET_MAX[_EXT] is
rejected.
This allows some old drives to work even if they aren't blacklisted.
