Fix ucastkey teardown for drivers that plumb clear keys or similar

Browse Source 
(e.g. ath): we must check the key index and not whether the key
points at a cipher other than "undef".  This looks like it's been
broken for a while.  Might be worth adding an explicit clear cipher
at some point though this would require changes to the usage of
IEEE80211_KEY_UNDEFINED.
