3.11.10.11 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniele Forsi <dforsi@gmail.com>

commit df602c2d2358f02c6e49cffc5b49b9daa16db033 upstream.

Even if the USB-to-ATAPI converter supported multiple LUNs, this
driver would always detect the same physical device or media because
it doesn't use srb->device->lun in any way.
Tested with an Hewlett-Packard CD-Writer Plus 8200e.
