iwlwifi: mvm: assign quota per virtual interface
Instead of assigning quota per used binding (channel) assign the same amount of quota for each virtual interface so that when there are more than two interfaces using more than one channel, we'll stay on the channels proportionally to the number of virtual interfaces using the channels.
