Subject: USB: lvtest: fix NULL-deref at probe

From: Johan Hovold <[email protected]>

commit 1dc56c52d2484be09c7398a5207d6b11a4256be9 upstream.

Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer should the probed device lack endpoints.

Note that this driver does not bind to any devices by default.
