This doesn't fix any bug that I know of. It just seems like probably
should use rx_nss instead of calculating it on our own (in case
something changes in the future).
A station may actually include operation mode change notification in
assoc request declaring it wants to use a different number of streams
than it actually supports as per its mcs map. That's not supported in
mac80211 though yet. Marek has posted some patches a few days ago but
it actually uses a different codepath from what I understand.
