libata: schedule probing after SError access failure during autopsy
If SError isn't accessible, EH can't tell whether hotplug has happened or not. Report SError read failure with AC_ERR_OTHER and schedule probing with hardreset. This will be mainly useful for PMPs. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
