net: mac802154: Fix symbol durations
There are two major issues in the logic calculating the symbol durations based on the page/channel: - The page number is used in place of the channel value. - The BIT() macro is missing because we want to check the channel value against a bitmask. Fix these two errors and apologize loudly for this mistake.
