Avoid changing wifi mac address when device does not support randomization

Devices without a vendor hal do not provide a way for the wifi framework
to get the factory mac address, so switching from a random mac to
the configured mac requires a reboot. So if mac randomization has not
been enabled in the device config, don't attempt to change the mac.
