It looks like the merge of Doug and Christoph's code dropped two calls
(unless the exit devfs_unregister was supposed to be removed).

Here's a patch for the addition of scsi_init_procfs, devfs_mk_dir and
bus_unregister calls, and a small reordering so calls in exit_scsi
match the reverse of those in init_scsi.
