Revert "usb: usb_storage: do not align length of request for CBW to maxp size"
This reverts commit 806e8f8fcc27e1753947bd9f059ba2316cf8f92a. To quote Alan Stern: The necessity for this patch has been under discussion. It turns out the UDC that Mian has been working on and Felipe's UDC have contradictory requirements. Mian's UDC driver wants a bulk-OUT transfer length to be shorter than the maxpacket size if a short packet is expected, whereas Felipe's UDC hardware always needs bulk-OUT transfer lengths to be evenly divisible by the maxpacket size. Mian has agreed to go back over the driver to resolve this conflict. This means we probably will not want this patch after all. (In fact, we may ultimately decide to change the gadget framework to require that bulk-OUT transfer lengths _always_ be divisible by the maxpacket size -- only the g_file_storage and g_mass_storage gadgets would need to be changed.)
