[PATCH] USB Storage: Save the SCSI residue value when auto-sensing
This patch (a regeneration of as173) saves the residue value of a command
when doing an auto-sense.
Not that it really matters much -- almost nobody looks at that value. But
it's definately incorrect the way it is, and this fixes it.
