esp32: don't fully reset the wifi device 

.. this makes reconnecting without a full reset not work.

Because this works on other generations of the esp32 (c2, c3, etc),
apply this behavior only to esp32.

After this change, it's possible to connect multiple times to wifi in
different runs of code.py or the repl after soft rebooting.
