[PATCH 1/3] driver: fix device remove order

[Sascha Hauer]

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.
