HID: roccat: Fix NULL pointer dereference when unloading module
Class was destroyed before starting the unregistering driver chain. Disconnecting a device from roccat chardev in this process then raised a NULL pointer dereference. Fixed this by destroying class after unregistering driver. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
