James Bottomley 427e59f09f [SCSI] make use of the residue value ...

USB sometimes doesn't return an error but instead returns a residue
value indicating part (or all) of the command wasn't completed.  So if
the driver _done() error processing indicates the command was fully
processed, subtract off the residue so that this USB error gets
propagated.
