cfg80211: fix sending WoWLAN TCP wakeup settings

commit e248ad30204eff6559b4d2d94d49d9d46c08185a upstream.

The code sending the current WoWLAN TCP wakeup settings in
nl80211_send_wowlan_tcp() is not closing the nested attribute,
thus causing the parser to get confused on the receiver side
in userspace (iw). Fix this.
