wifi: mac80211: set assoc_encrypted for EPP associations

Browse Source 
Populate the assoc_encrypted field in cfg80211_rx_assoc_resp_data
for mac80211-based drivers to indicate that the entire (re)association
exchange was encrypted.

When epp_peer is set, mac80211 enforces that unprotected
(Re)Association Request/Response frames are dropped. This ensures that
by the time the (Re)Association Response is processed, the entire
exchange was transmitted encrypted over the air.

Add support to populate assoc_encrypted based on epp_peer flag.
