qcacld-3.0: Fix STA state handling in case of WEP

qcacld-2.0 to qcacld-3.0 propagation

Handle STA State in hdd_RoamSetKeyCompleteHandler for WEP case.
In WEP case Key are set in following order.
1)Group key
2)Unicast Key
In WEP case STA was moved to AUTHENTICATED prior to
setting the unicast key and it was resulting in sending
few un-encrypted packet. Now STA state will be moved to
AUTHENTICATED after we set the unicast and group
key in WEP case.
