wifi: rtw89: mcc: update entire plan when courtesy config changes

Browse Source 
MCC has a courtesy mechanism which allows one role to use another's
duration in a given cycle. Courtesy mechanism will be enabled when
one role has a not perfect duration. Otherwise, not. When MCC updates,
duration of each role will be re-calculated. And then, the new courtesy
config might be different from the old one. However, to change courtesy
config, the entire MCC plan requires to be renewed when MCC updates.
