In ieee80211_build_hdr(), IEEE80211_TX_CTL_REQ_TX_STATUS is checked
in ctrl_flags, which is wrong - IEEE80211_TX_CTL_REQ_TX_STATUS is in
info->flags, so the check is for IEEE80211_TX_CTRL_PORT_CTRL_PROTO
instead. This works out OK because the only place setting _that_ at
a point before this gets called is in fact ieee80211_tx_control_port()
which was intended here. This is actually needed for correctness, if
jt were checking info->flags instead, TDLS would fill/leak the status
frames created here.
However, we can just fix it by using the cookie instead, that'll be
set for PREAUTH frames via ieee80211_tx_control_port() as well, and
no other frames.
Additionally, the code also erroneously set it, but that just caused
preauth frames to get it set, since storing the ACK SKB will also set
the correct flag. Drop this assignment entirely.
