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.
