No, I'd guess that the problem is just that __scsi_remove_device()
sets queuedata to NULL. Afaik, both sdev and the queue actually stay
around.

That said, I don't have very high opinions of some of the SCSI code.
And that's me being polite. The thing is a overcomplicated mess of
indirection and pointers back-and-forth. The refcounting is crazy
and/or impossible, since the pointers really do go back-and-forth.
