commit "mac80211: unify SW/offload remain-on-channel"
moved the cookie assignment from ieee80211_mgmt_tx()
to ieee80211_start_roc_work(). But the latter is only
called where offchannel is needed. If offchannel isn't
needed/used, a uninitialized cookie value would be returned
to userspace.
This patch sets the cookie value when offchannel isn't used.
