The ACTIVITY and ERROR signals were reversed in the original commit. Fix that so that hard drive activity does not show up on the error light, and attempts to indicate that the hard drive is failing do not show up as hard drive activity. This fixes a fairly serious functional bug in the driver, but failing to apply this patch will not cause any stability issues on the system.
