mac80211: fix offchannel TX cookie matching

commit 28a1bcdb57d50f3038a255741ecc83e391e5282e upstream.

When I introduced in-kernel off-channel TX I
introduced a bug -- the work can't be canceled
again because the code clear the skb pointer.
Fix this by keeping track separately of whether
TX status has already been reported.
