qcacld-3.0: Release pre-cac adapter's mac addr once cac finishes

As per the design pre-cac adapter will be assigned temporary mac address
till it finishes the CAC operation. Once the cac operation finishes
with success or failure, pre-cac adapter's mac address needs to be released.

In failure case, pre-cac adapter's mac address is getting released but
in success case, it is not released which results in to error code -22 at upper
layer.
