wl12xx: use a bitmask instead of list of booleans in scanned_ch
We were using an array of booleans to mark the channels we had already
scanned. This was causing a sparse error, because bool is not a type
with defined size. To fix this, use bitmasks instead, which is much
cleaner anyway.
Thanks Johannes Berg for the idea.
