I've run into an issue where iwn(4) fails to init the hardware.
Running 'ifconfig iwn0 scan' resulted in:
setting configuration
iwn0: fatal firmware error

iwn0: RXON command failed
iwn0: could not configure device
iwn0: could not load firmware .data section
iwn0: could not load firmware
iwn0: could not initialize hardware
A debug printf revealed the rxon command channel was set to zero:
iwn_config: rxon chan 0 flags 40008000 cck f ofdm ff
I haven't been able to reproduce the problem with the diff below.
Note that this code runs during hardware initialization only.
It shouldn't really matter what channel we set here as long as
it isn't zero.
Fix a misplaced curly brace while here...
ok?
