libata: -ENODEV during prereset isn't an error
During prereset, -ENODEV return from ata_wait_ready() is not an error. This causes unnecessary bug message on controllers which uses 0xff to indicate empty port. Fix it. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
