Currently we preassign gadget endpoints to raw-gadget endpoints during
initialization. Fix resetting this assignment in raw_ioctl_ep_disable(),
otherwise we will get null-ptr-derefs when an endpoint is reenabled.

Felipe, this is technically a fix for "usb: raw-gadget: fix gadget
endpoint selection", which AFAICS is already in your testing/fixes tree.
Please let me know if you would like me resend that patch with this fix
folded in.
