nl80211: clear skb cb before passing to netlink
commit bd8c78e78d5011d8111bc2533ee73b13a3bd6c42 upstream.
In testmode and vendor command reply/event SKBs we use the
skb cb data to store nl80211 parameters between allocation
and sending. This causes the code for CONFIG_NETLINK_MMAP
to get confused, because it takes ownership of the skb cb
data when the SKB is handed off to netlink, and it doesn't
explicitly clear it.
Clear the skb cb explicitly when we're done and before it
gets passed to netlink to avoid this issue.
