    mac80211: don't validate unchanged AP bandwidth while tracking

    The MLME code in mac80211 must track whether or not the AP changed
    bandwidth, but if there's no change while tracking it shouldn't do
    anything, otherwise regulatory updates can make it impossible to
    connect to certain APs if the regulatory database doesn't match the
    information from the AP. See the precise scenario described in the
    code.

    This still leaves some possible problems with CSA or if the AP
    actually changed bandwidth, but those cases are less common and
    won't completely prevent using it.

    This fixes https://bugzilla.kernel.org/show_bug.cgi?id=70881
