    wifi: cfg80211: adjust allocation of colocated AP data
    
    In 'cfg80211_scan_6ghz()', an instances of 'struct cfg80211_colocated_ap'
    are allocated as if they would have 'ssid' as trailing VLA member. Since
    this is not so, extra IEEE80211_MAX_SSID_LEN bytes are not needed.
    Briefly tested with KUnit.
