evdev: plug a potential memleak

For touchpads, device->dispatch is set up when exiting
evdev_handle_device() and a potential source for a memleak.
This can't actually happen at the moment, as evdev_handle_device() won't
fail for touchpads after setting up the dispatch but prevent this from
happening in the future.
