mac80211: add skb length sanity checking
We just found a bug in zd1211rw where it would reject
packets in the ->tx() method but leave them modified,
which would cause retransmit attempts with completely
bogus skbs, eventually leading to a panic due to not
having enough headroom in those.
This patch adds a sanity check to mac80211 to catch
such driver mistakes; in this case we warn and drop
the skb.
