Wei Ming Chen 0d48aee69c usb: raw-gadget: return -EINVAL if no proper ep address available
If we try to use raw_ioctl_ep_enable() for ep5in on a hardware that
only support from ep1-ep4 for both in and out direction, it will return
-EBUSY originally.

I think it will be more intuitive if we return -EINVAL, because -EBUSY
sounds like ep5in is not available now, but might be available in the
future.
