In some cases it was observed, that a first ping wasn't answered (because the NA wasn't handled by the host). This was due to a bug in the neighbor cache, that did not recognize `entry->iface == KERNEL_PID_UNDEF` as a legal entry (which may be the case if the state is e.g. INCOMPLETE). This PR fixes that.
