This is basically revert of:

commit 35a6eb36520b938742d8680fd8d821df20982ced

    iwlwifi: resending QoS command when HT changes
    
    "mac80211: Fix WMM driver queue configuration"
    inadvertedly broke iwlwifi, because now mac80211
    configures the QoS settings before assoc, and
    therefore before HT. Thus, iwlwifi no longer told
    the device about the HT setting, which it needs
    to -- and thus throughput went down a lot. Fix
    this by resending the QoS command to the device
    not only when QoS/WMM settings change, but also
    when HT changes.

Does problem that 35a6eb36520b938742d8680fd8d821df20982ced fixed
gone now? How?
