ath9k: connectivity is lost after Group rekeying is done

Browse Source 
Connectivtiy is lost after Group rekeying is done. The keytype
maintained by ath9k is reset when group key is updated. Though
sc_keytype can be reset only for broadcast key the proper fix
would be to use mac80211 provided key type from txinfo during
xmit and get rid of sc_keytype from ath9k ath_softc.
