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.
