When bringing an interface up, and thus perhaps having just powered it

Browse Source 
on (e.g. cardbus), write the wep keys to the card.  Fixes problem of
receiving gibberish if one has set wep keys before bringing the
interface up, and also after ifconfig ath0 down; ifconfig ath0 up.

(Tested with current from 20050926 with local mods, and discussed with
sam@ and dyoung@.  This is not 100% right, but significantly better
than before.  Really we should have an interator in net80211 to repush
all key state, include per-node keys.)
