Request for testing for iwlwifi

Hi,

could some of you please test this small patch and let me know:

https://people.freebsd.org/~bz/tmp/20220825-01-lkpi-bssid.diff

In theory this should be fine.  But it does crash firmware on one of my
test machines reliably while other cards are okay.  If the firmware crash
happens it should be in scan_to_auth with the backtrace after the firmware
register dump as below.

It's a prereq for enabling some more of iwlwifi so it would be good
to know that it's a one-off problem here rather than more people seeing
my problem.
