After updating to -current built from source date 2021.03.07.10.56.18,
I can confirm that the system no longer panics. It still doesn't
work, though - it completes a few scans, but then logs "wpi0: fatal
firmware error" and stops scanning. I figure that's a separate bug,
so I will close this PR and file a new one.
