There are two bugs in disabled port handling.

The first bug makes the PATA channel considered disabled but the
second bug saves the day by returning 0. The net result is that cable
is always left at ATA_CBL_UNKNOWN. This results in false 80c
configuration and thus transfer errors.
This patch fixes both bugs.
