    cfg80211: remove enum station_info_flags

    This is really just duplicating the list of information that's
    already available in the nl80211 attribute, so remove the list.
    Two small changes are needed:
     * remove STATION_INFO_ASSOC_REQ_IES complete, but the length
       (assoc_req_ies_len) can be used instead
     * add NL80211_STA_INFO_RX_DROP_MISC which exists internally
       but not in nl80211 yet

    This gets rid of the duplicate maintenance of the two lists.
