Improve device mode (gadget) stall handling.
Some hardware easily comes out of sync with regard to whether the current or
the next control transfer should be stalled, if a stall command is always
issued before receiving the SETUP packet. After this patch the stall command
will only be issued when a transfer should actually be stalled.
