iwn(4) stops being able to find any network at all with r1.20 of if_iwn.c (and
if_iwnreg.h r1.4). Reverting to r1.19 and r1.3 fixes the issue.

I have two dmesg excerpts; one for a GENERIC kernel from monday with r1.19
and one for an almost-GENERIC (only options EST_DEBUG added) from today with
r1.20. There are no significant differences, except for the number of errors
reported for iwn0, but those differ between boots of the same kernel as well
as resuming from ACPI S3 suspend. But I guess that's due to the driver being
in alpha stages, or something. If the excerpts are deemed useful, just ask.
Try to connect to 802.11 networks with an iwn(4) adapter on amd64 with r1.20
Revert if_iwn.c to r1.19 and if_iwnreg.h to r1.3.
