[PATCH] Remove unnecessary addition operations from usb/core/hub.c

[Telemaque Ndizihiwe]

This Patch removes unnecessary addition operations from
usb/core/hub.c in kernel 2.6.10.

	usb_disable_endpoint(udev, 0 + USB_DIR_IN);   //replaced by
	usb_disable_endpoint(udev, USB_DIR_IN);

	usb_disable_endpoint(udev, 0 + USB_DIR_OUT);  //replaced by	
	usb_disable_endpoint(udev, USB_DIR_OUT);
