qcacld-3.0: Set correct wep key for sap mode

When wep_default_key is not set as 0 in hostapd.conf, wep key with
key id 0 should not be sent to FW when new station is connected.
Wep key with key id specified in hostapd.conf should be sent to FW.

To fix this issue, wep default key id should be saved for sap mode.
When reference station is connected, set default key id related key
to FW with TX_USAGE flag.
