It longer needs that private copy, true, but we will probably want to keep
it anyhow.
It's not very long. The important part is only 3 or 4 statements.
It includes usb-storage's infamous verbose debugging messages. :-)
It doesn't require the overhead of allocating a new URB or control
request structure, nor of performing the DMA mapping.
It provides a way to cancel the request without waiting for a
timeout.
