USB: remove the URB_NO_FSBR flag
The URB_NO_FSBR flag has never really been used. It was introduced as a potential way for UHCI to minimize PCI bus usage (by not attempting full-speed bulk and control transfers more than once per frame), but the flag was not set by any drivers. There's no point in keeping it around. This patch simplifies the API by removing it. Unfortunately, it does have to be kept as part of the usbfs ABI, but at least we can document in include/uapi/linux/usbdevice_fs.h that it doesn't do anything.
