UPSTREAM: USB: dummy-hcd: use usb_urb_dir_in instead of usb_pipein
(Upstream commit 6dabeb891c001c592645df2f477fed9f5d959987.) Commit fea34091 ("USB: add direction bit to urb->transfer_flags") has added a usb_urb_dir_in() helper function that can be used to determine the direction of the URB. With that patch USB_DIR_IN control requests with wLength == 0 are considered out requests by real USB HCDs. This patch changes dummy-hcd to use the usb_urb_dir_in() helper to match that behavior.
