NullFunc packets should never be duplicate just like QoS-NullFunc packets.
We saw a client that enters / exits power save with NullFunc frames (and not with QoS-NullFunc) despite the fact that the association supports HT. This specific client also re-uses a non-zero sequence number for different NullFunc frames. At some point, the client had to send a retransmission of the NullFunc frame and we dropped it, leading to a misalignment in the power save state. Fix this by never consider a NullFunc frame as duplicate, just like we do for QoS NullFunc frames.

This has already been sent, it is in net.git already :)
Oops, sorry, my bad. I obviously forgot to look it up before sending.
