Can we _please please_ drop the idea of making a unit number out of
a <target,lun>?  Autoconfiguration dynamically assigns the unit numbers
based on locators configuration entries, does device cloning, etc.

The suggestion of tying disk unit number to very specific-to-what-the-disk-
sits-on locator information is contrary to how we've been assigning unit
numbers for ... many years now.
