[PATCH] libata: fix class handling in ata_bus_probe()
ata_bus_probe() didn't set classes[] properly for port disabled case
of ->phy_reset() compatibility path. This patch moves classes[]
initialization and normalization out of ->probe_reset block such that
it applies to both ->probe_reset and ->phy_reset paths.
