Add the missing endpoint sanity check to prevent a NULL-pointer dereference should a malicious device lack the expected endpoints. Note that the driver has a broken endpoint-lookup helper, lan78xx_get_endpoints(), which can end up accepting interfaces in an altsetting without endpoints as long as *some* altsetting has a bulk-in and a bulk-out endpoint.
