nl80211: Add flag attribute for RRM connections
Add a flag attribute to use in associations, for tagging the target connection as supporting RRM. It is the responsibility of upper layers to set this flag only if both the underlying device, and the target network indeed support RRM. To be used in ASSOCIATE and CONNECT commands.
