nl80211: fix missing nesting

commit 95a6ccbb46c70cff376684c752831c014c87029d

    cfg80211/mac80211: extensible frame processing

introduced a netlink bug that caused parsing errors
in userspace because it forgot to close a nesting,
which would advertise a nesting length of zero to
userspace, which then completely threw off parsing
and led to

	Illegal nla->nla_type == 0

being printed by libnl.
