[Paul Menzel (Code Review)]

device/cardbus: Check dev->link_list to avoid accessing garbage

While debugging problems on a Lenovo T60 device, Kyösti noticed a NULL
pointer access. `dev->link_list` can be NULL, as resource scanning
`scan_resources` is not implemented. So, add a check to avoid a NULL
pointer access.
