Johannes Berg bd8c78e78d nl80211: clear skb cb before passing to netlink 
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.
