wifi: nl80211: fixes to FILS discovery updates
Add a new flag 'update' which is set to true during start_ap() if (and only if) one of the following two conditions are met: - Userspace passed an empty nested attribute which indicates that the feature should be disabled and templates deleted. - Userspace passed all the parameters for the nested attribute. Existing configuration will not be changed while the flag remains false. Add similar changes for unsolicited broadcast probe response transmission.
