We need to delete authorized and wme_sta flags, because these flags are set 
below:

1956         multicast = is_multicast_ether_addr(hdr.addr1);
1957         if (!multicast) {
1958                 sta = sta_info_get(sdata, hdr.addr1);
1959                 if (sta) {
1960                         authorized = test_sta_flag(sta, 
WLAN_STA_AUTHORIZED);
1961                         wme_sta = test_sta_flag(sta, WLAN_STA_WME);
1962                 }
1963         }
