wifi: iwlwifi: mld: update the P2P device mac before starting the GO

When a GO is started, the P2P device mac is updated to indicate
that frames for the P2P device mac should be filtered in while
the GO is active. However, this configuration is done after the GO is
already started so it doesn't take effect. Fix it by updating the
P2P device mac before adding the broadcast station, which actually
starts the GO.
