dix/devices: add devices in proper forward order

Browse Source 
Add devices in forward order with the normal linked list convention.
Previously, AddInputDevice would add all the devices in reverse order to
off_devices, before they were added again in reverse order to devices with
EnableDevice.
This just makes both work in forward order, which provides the ordering as
you'd expect when hotplugging devices (i.e. adds them to the head, not the
tail).
