This oops traces back into the scsi stack, right? The spaghetti of
trying to get things to work right with the scsi stack is getting to be
a pain. I guess USB doesn't have too many problems since it does a
scsi-host per device, but that's not as easy with sbp2 and 1394, since a
single sbp2 device can have multiple LUN's, and it's just easier to
treat that as one scsi host.

I can't reproduce it, but I'll try to get into the logic of sbp2 device
removal again to see if I can find out where and why this is occuring.
