pata_isapnp: Don't use invalid I/O ports
The test for 2nd I/O port validity is broken (reversed): On devices with no control port, the driver attempts to use invalid port 0, resulting in logs full of bad_io_access errors. On devices with control port, the driver does not use it. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tejun Heo <tj@kernel.org>
