qcacld-3.0: Return failure if mac provision failed

In current code, if mac_provision is enabled, the
checking for return value of hdd_platform_wlan_mac
will be bypassed, this is not the intention.

Change as:
   when mac_provision is enabled, it returns
   only when getting mac address from platform failed.
