After a card is removed, ide_release() will unregister the net
device, and release the PCMCIA configuration. If the device is
still open, this will be postponed until it is closed.

stuff to run after an event is received. A CARD_REMOVAL event
also sets some flags to discourage the ide drivers from
talking to the ports.
