[MAC rand] cleanup obsolete code

These logic were only needed in early stage of Q when we were creating
the randomized MAC address when making connections.

Now that per-SSID randomized MAC is generated when networks are added into
WifiConfigManager, this is no longer needed.

Bug: 137799272
Test: unit test
Test: manually tested on device by running through the standard
connection scenarios
