Did you try again to switch back to iwlwifi?
What happens if you are on a running iwm setup and then do the devctl
detach, set driver dance?
So on my current running iwm setup without changing anything else I did
the devtl detach, set driver dance which failed as follows:

You could try a devctl reset ... between detach and set driver.
Also you could try to stop the iwm0 (wlan0) before detaching and see if
that gets a clean(er) shutdown (service netif destroy wlan0 && devctl
detach ...)
