wifi: cfg80211: modify prototype for change_beacon
Modify the prototype for change_beacon() in struct cfg80211_op to
accept cfg80211_ap_settings instead of cfg80211_beacon_data so that
it can process data in addition to beacons.
Modify the prototypes of ieee80211_change_beacon() and driver specific
functions accordingly.

[while at it, remove pointless "if (info)" check in tracing that just
makes all the lines longer than they need be - it's never NULL]
