    LinuxKPI: 802.11: set IEEE80211_MIN_ACTION_SIZE according to struct
    
    IEEE80211_MIN_ACTION_SIZE came up in the mt76 vendor subtree merge
    as one of the non-mechanical changes which made me look.
    Rather than (incorrectly) hand counting the offset from the beginning
    of a frame, use the offset from the beginning of struct ieee80211_mgmt.
