[PATCH] libata: fix missing classes[] initialization in ata_bus_probe()
ata_bus_probe() didn't initialize classes[] properly with
ATA_DEV_UNKNOWN. As ->probe_reset() is allowed to leave @classes
alone when no device is present, this results in garbage class values.
ATM, the only affected driver is ata_piix.
