driver: fix device remove order 

The active list is supposed to collect active devices in the
opposite order they are probed. This is used to remove the
devices in the correct order in devices_shutdown. The order
is wrong though when in a drivers probe function other devices
are registered. To get the order right we have to add the new
device to the active list before it is probed.
