USB: dummy-hcd: use usb_urb_dir_in instead of usb_pipein
commit 6dabeb891c001c592645df2f477fed9f5d959987 upstream.
Commit fea3409112a9 ("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.
