wifi: mac80211: stop using ieee80211_mgmt_tx_cookie()

Now that cfg80211 pre-assigns the cookie before calling into mac80211,
stop calling ieee80211_mgmt_tx_cookie() in all affected paths:

- ieee80211_start_roc_work(): for normal ROC use the pre-assigned value
  directly instead of generating a new one.
- ieee80211_attach_ack_skb(): the cookie is already set by the caller;
  remove the ieee80211_mgmt_tx_cookie() call and store it in the ack
  SKB as-is. This covers both mgmt_tx and probe_peer since both call
  ieee80211_attach_ack_skb().
- ieee80211_mgmt_tx(): the dummy 0xffffffff assignment for the
  dont_wait_for_ack case is no longer needed; cfg80211_assign_cookie()
  guarantees a non-zero value which is sufficient for the internal
  ROC vs mgmt-tx distinction.
- ieee80211_store_ack_skb(): same fix for the tx_control_port path.

With no remaining callers, remove ieee80211_mgmt_tx_cookie() and the
roc_cookie_counter field from struct ieee80211_local.
