Well based on some of the info from
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249287 I powered-off,
unplugged it from the mains and left it for like 15 minutes.
Powered back on and wlan0 got created again using iwm0 as parent and my
wifi is working again.

I did add to loader.conf prior to the power down:
if_iwm_load="YES"
iwm9000fw_load="YES"

I know I shouldn't have to do this (never did before) but given my
situation I was willing to try about anything.

Here's the iwm info from the last verbose boot:

Now that I'm back to square one I can try again with iwlwifi, if that is
advised?
