pcmcia: dev_node removal (drivers with unregister_netdev check)

Browse Source 
As a third step, remove any usage of dev_node_t from drivers which
only wrote to this typedef/struct, except to determine whether
register_netdev() succeeded previously. However, the function calling
unregister_netdev() was only ever called by the PCMCIA core if
register_netdev() succeeded previously. The lonely exception was
easily fixed.
