wifi: cfg80211: Allow AP/P2PGO to indicate port authorization to peer STA/P2PClient
In 4way handshake offload, cfg80211_port_authorized enables driver
to indicate successful 4way handshake to cfg80211 layer. Currently
this path of port authorization is restricted to interface type
NL80211_IFTYPE_STATION and NL80211_IFTYPE_P2P_CLIENT. This patch
extends the support for NL80211_IFTYPE_AP and NL80211_IFTYPE_P2P_GO
interfaces to authorize peer STA/P2P_CLIENT, whenever authentication
is offloaded on the AP/P2P_GO interface.
