pata_jmicron: fix disabled port handling in jmicron_pre_reset()
There are two bugs in disabled port handling.
* test in PORT_PATA0 is reversed
* ->prereset should return -ENOENT for disabled ports not 0
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.
