wifi: rtw89: chan: recalc MLO DBCC mode based on current entity mode

Since MLD vif can do MLSR switch, it may not always run on HW band 0.
But when preparing MCC for MLD + P2P, P2P vif needs to use HW band 0
to handle connection, i.e. uses of HW bands may be different by vif.

The current major role/vif can be indicated through entity mode. So,
based on it, recalculate MLO DBCC mode to change use of HW band.
