USB: dummy-hcd: use usb_urb_dir_in instead of usb_pipein

Browse Source 
Commit fea3409112 ("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.
