iwlwifi: split the regulatory rules when the bandwidth flags require it
When we create a regulatory domain out of an MCC notification, we need to make sure that all the channels in the rule have the exact same properties. The current code mixes channel 36 and 40 although 36 can be a control channel with HT40+ (36, 40) whereas 40 can't be a control channel with HT40+ since (40, 44) is invalid. Because of that, cfg80211 would allow to connect in 40MHz to APs that are configured to channel 40 HT40+ and that made our firmware assert. Fix this by checking the bandwidth flags before taking the decision if the rule should be split. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299 partly.
