For non-QoS nullfunc packets we currently do the duplicate detection,
which seems a bit wrong. Fix the code to check for _any_ instead of
just _qos_ nullfunc.

Also remove setting the RX_FLAG_DUP_VALIDATED flag, we haven't done
anything here; in particular, we haven't checked for multicast in an
MLO scenario.
