Veaceslav Falico 6859e7df6d netdev: remove potentially harmful checks ...

Currently we're checking a variable for != NULL after actually
dereferencing it, in netdev_lower_get_next_private*().

It's counter-intuitive at best, and can lead to faulty usage (as it implies
that the variable can be NULL), so fix it by removing the useless checks.
