usb: fixes for v3.18-rc5

Just one fix here on dwc3 which fixes a minor
bug caused by a fix that went in this v3.18-rc
cycle.

The corner case is minimal as it can only be
reproduced with back-to-back Setup transfers
(without starting data or status phase) by
means of a LeCroy USB Trainer, where we can
generate USB packets any way we like.
