RNR: Update Beacon frames for 6 GHz colocation

Browse source 
Update 2.4/5 GHz Beacon frames every time Beacon frames for co-located 6
GHz AP(s) are set. This is required for 6 GHz out-of-band discovery so
that lower band Beacon frames will include RNR element with 6 GHz AP
information irrespective of the AP bring-up order. Similarly, RNR is
included in FILS Discovery frames by default in 6 GHz-only mode,
updating the Beacon frames will remove it when co-located 2.4/5 GHz
interfaces are brought up.

This change also ensures that the changes in 6 GHz AP configuration such
as new channel and bandwidth get reflected in the lower bands Beacon
frames.
