net80211: remove (optional) RSN from preobereq

Browse Source 
802.11i-2004 did not specify that RSN can be added to the probereq,
only to the proberesp (and others) yet it was added in what seems was
b032f27c36 (multi-BSS support).
802.11-2020 does not list the IE either for probereq so remove it.
