ath9k: connectivity is lost after Group rekeying is done
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.
