Applied.

While reviewing this I noticed that slip_devs[], along with the
arbitrary slip_maxdev limit, can be removed and replaced with
a simply linked list.

All the array is used for it proper teardown during module unload.
This is made even more clear by the fact that the index stored
in dev->base_addr is never ever used.
