This routine is only used to post-filter the channels so I don't
think we need to check the band. It's mostly just to weed out all
of the 10 mhz-spaced 5 ghz channels we used to export.

Ok I was also going to complain that some channel numbers < 14 were
valid in the 5 ghz band but you know that :)
