Update Probe Response template on BSS color change

Browse source 
When AP is beaconing only on the 6 GHz band and unsol_bcast_presp
interval is set, AP sends unsolicited broadcast Probe Response frames
for in-band discovery. hostapd sent the Probe Response template for this
frame only when setting a new Beacon frame template.

Extend this to update the Probe Response template during BSS color
change.
