FILS discovery and unsolicited broadcast probe response transmissions
are configured as part of NL80211_CMD_START_AP, however both stop
after userspace uses the NL80211_CMD_SET_BEACON command as these
attributes are not processed as part of this command.
- Add the missing implementation in nl80211 and mac80211.
- Modify the local variable in nl80211_set_beacon() and input parameter
to rdev_change_beacon() from type struct cfg80211_beacon_data to
type struct cfg80211_ap_settings to support the new processing.
- Modify ieee80211_change_beacon() to reflect the new input parameter type.
- Modify driver specific functions pointed by change_beacon to
reflect the new input parameter type.

v4:
- Modifications to all driver specific function pointers.
- Also included all files in a single patch instead of splitting as per
the modules because otherwise compilation fails with changes in only
net/wireless and include/net directories.
