mac80211: add missing key checkmaster-2010-01-22
ieee80211_tx_h_select_key might decide that a frame
need not be encrypted at all, in which case it will
clear tx->key. In that case it may crash if a key
was previously selected, e.g. as the default key.
This is also due to my patch
"mac80211: move control.hw_key assignment".
