kern/170573: [iwi] Intel 2200BG iwi NIC hangs with need multicast callback and firmware error

[Yuval Prag]

Hi See attached updates for the PR in the subject

I have tried to use the latest NIC driver from the repository 1.72.6 and I
still have the same error end the device file to connect reliably to the
network
see attached files with error messages and some instrumentation I added to
stop the printing because it polluted the /var/log/messages with the errors

if there is any other way of updating the PR please explain how
Thanks
Yuval
